Converted most forms to use elgg_view_form (therefore also moved the views to forms/*). Some views are left that _only_ do elgg_view_form, so I wonder if those should even be kept around.

+The files in this directory represent the default Minify setup designed to ease
+integration with your site. This app will combine and minify your Javascript or
+CSS files and serve them with HTTP compression and cache headers.
+
+
+RECOMMENDED
+
+It's recommended to edit config.php to set $min_cachePath to a writeable
+(by PHP) directory on your system. This will improve performance.
+
+
+GETTING STARTED
+
+The quickest way to get started is to use the Minify URI Builder application
+on your website: http://example.com/min/builder/
+
+
+MINIFYING A SINGLE FILE
+
+Let's say you want to serve this file:
+  http://example.com/wp-content/themes/default/default.css
+
+Here's the "Minify URL" for this file:
+  http://example.com/min/?f=wp-content/themes/default/default.css
+
+In other words, the "f" argument is set to the file path from root without the 
+initial "/". As CSS files may contain relative URIs, Minify will automatically
+"fix" these by rewriting them as root relative.
+
+
+COMBINING MULTIPLE FILES IN ONE DOWNLOAD
+
+Separate the paths given to "f" with commas.
+
+Let's say you have CSS files at these URLs:
+  http://example.com/scripts/jquery-1.2.6.js
+  http://example.com/scripts/site.js
+
+You can combine these files through Minify by requesting this URL:
+  http://example.com/min/?f=scripts/jquery-1.2.6.js,scripts/site.js
+
+
+SIMPLIFYING URLS WITH A BASE PATH
+
+If you're combining files that share the same ancestor directory, you can use
+the "b" argument to set the base directory for the "f" argument. Do not include
+the leading or trailing "/" characters.
+
+E.g., the following URLs will serve the exact same content:
+  http://example.com/min/?f=scripts/jquery-1.2.6.js,scripts/site.js,scripts/home.js
+  http://example.com/min/?b=scripts&f=jquery-1.2.6.js,site.js,home.js
+
+
+MINIFY URLS IN HTML
+
+In (X)HTML files, don't forget to replace any "&" characters with "&amp;".
+
+
+SPECIFYING ALLOWED DIRECTORIES
+
+By default, Minify will serve any *.css/*.js files within the DOCUMENT_ROOT. If
+you'd prefer to limit Minify's access to certain directories, set the 
+$min_serveOptions['minApp']['allowDirs'] array in config.php. E.g. to limit 
+to the /js and /themes/default directories, use:
+
+$min_serveOptions['minApp']['allowDirs'] = array('//js', '//themes/default');
+
+
+GROUPS: FASTER PERFORMANCE AND BETTER URLS
+
+For the best performance, edit groupsConfig.php to pre-specify groups of files 
+to be combined under preset keys. E.g., here's an example configuration in 
+groupsConfig.php:
+
+return array(
+    'js' => array('//js/Class.js', '//js/email.js')
+);
+
+This pre-selects the following files to be combined under the key "js":
+  http://example.com/js/Class.js
+  http://example.com/js/email.js
+  
+You can now serve these files with this simple URL:
+  http://example.com/min/?g=js
+  
+
+GROUPS: SPECIFYING FILES OUTSIDE THE DOC_ROOT
+
+In the groupsConfig.php array, the "//" in the file paths is a shortcut for
+the DOCUMENT_ROOT, but you can also specify paths from the root of the filesystem
+or relative to the DOC_ROOT: 
+
+return array(
+    'js' => array(
+        '//js/file.js'            // file within DOC_ROOT
+        ,'//../file.js'           // file in parent directory of DOC_ROOT
+        ,'C:/Users/Steve/file.js' // file anywhere on filesystem
+    )
+);
+
+
+FAR-FUTURE EXPIRES HEADERS
+
+Minify can send far-future (one year) Expires headers. To enable this you must
+add a number to the querystring (e.g. /min/?g=js&1234 or /min/f=file.js&1234) 
+and alter it whenever a source file is changed. If you have a build process you 
+can use a build/source control revision number.
+
+If you serve files as a group, you can use the utility function Minify_groupUri()
+to get a "versioned" Minify URI for use in your HTML. E.g.:
+
+<?php
+// add /min/lib to your include_path first!
+require $_SERVER['DOCUMENT_ROOT'] . '/min/utils.php';
+
+$jsUri = Minify_groupUri('js'); 
+echo "<script type='text/javascript' src='{$jsUri}'></script>";
+
+
+DEBUG MODE
+
+In debug mode, instead of compressing files, Minify sends combined files with
+comments prepended to each line to show the line number in the original source
+file. To enable this, set $min_allowDebugFlag to true in config.php and append
+"&debug=1" to your URIs. E.g. /min/?f=script1.js,script2.js&debug=1
+
+Known issue: files with comment-like strings/regexps can cause problems in this mode.

+<p>Place this URI in your HTML to serve the files above combined, minified, compressed and
+with cache headers.</p>
+<table id=uriTable>

+	<tr><th>HTML</th><td><input id=uriHtml type=text size=100 readonly></td></tr>
+</table>
+
+<h2>How to serve these files as a group</h2>
+<p>For the best performance you can serve these files as a pre-defined group with a URI
+like: <code><span class=minRoot>/min/?</span>g=keyName</code></p>
+<p>To do this, add a line like this to /min/groupsConfig.php:</p>
+
+<pre><code>return array(
+	<span style="color:#666">... your existing groups here ...</span>
+<input id=groupConfig size=100 type=text readonly>
+);</code></pre>
+
+<p><em>Make sure to replace <code>keyName</code> with a unique key for this group.</em></p>

+<h3>Find URIs on a Page</h3>
+<p>You can use the bookmarklet below to fetch all CSS &amp; Javascript URIs from a page
+on your site. When you active it, this page will open in a new window with a list of
+available URIs to add.</p>
+
+<p><a id=bm>Create Minify URIs</a> <small>(right-click, add to bookmarks)</small></p>
+</div>
+
+<h3>Combining CSS files that contain <code>@import</code></h3>
+<p>If your CSS files contain <code>@import</code> declarations, Minify will not 
+remove them. Therefore, you will want to remove those that point to files already
+in your list, and move any others to the top of the first file in your list 
+(imports below any styles will be ignored by browsers as invalid).</p>
+<p>If you desire, you can use Minify URIs in imports and they will not be touched
+by Minify. E.g. <code>@import "<span class=minRoot>/min/?</span>g=css2";</code></p>

+   * Converts to and from JSON format.
+   *
+   * JSON (JavaScript Object Notation) is a lightweight data-interchange
+   * format. It is easy for humans to read and write. It is easy for machines
+   * to parse and generate. It is based on a subset of the JavaScript
+   * Programming Language, Standard ECMA-262 3rd Edition - December 1999.
+   * This feature can also be found in  Python. JSON is a text format that is
+   * completely language independent but uses conventions that are familiar
+   * to programmers of the C-family of languages, including C, C++, C#, Java,
+   * JavaScript, Perl, TCL, and many others. These properties make JSON an
+   * ideal data-interchange language.
+   *
+   * This package provides a simple encoder and decoder for JSON notation. It
+   * is intended for use with client-side Javascript applications that make
+   * use of HTTPRequest to perform server communication functions - data can
+   * be encoded into JSON notation for use in a client-side javascript, or
+   * decoded from incoming Javascript requests. JSON format is native to
+   * Javascript, and can be directly eval()'ed with no further parsing
+   * overhead
+   *
+   * All strings should be in ASCII or UTF-8 format!

+/**
+ * jsmin.php - PHP implementation of Douglas Crockford's JSMin.
+ *
+ * This is a direct port of jsmin.c to PHP with a few PHP performance tweaks and
+ * modifications to preserve some comments (see below). Also, rather than using
+ * stdin/stdout, JSMin::minify() accepts a string as input and returns another
+ * string as output.
+ * 
+ * Comments containing IE conditional compilation are preserved, as are multi-line
+ * comments that begin with "/*!" (for documentation purposes). In the latter case
+ * newlines are inserted around the comment to enhance readability.
+ *
+ * PHP 5 or higher is required.
+ *
+ * Permission is hereby granted to use this version of the library under the
+ * same terms as jsmin.c, which has the following license:

+     * headers, allowing shared caches to cache the output. (default true)
+     * 
+     * 'quiet' : set to true to have serve() return an array rather than sending

+     * 
+     * 'encodeOutput' : set to false to disable content encoding, and not send
+     * the Vary header (default true)
+     * 
+     * 'encodeMethod' : generally you should let this be determined by 
+     * HTTP_Encoder (leave null), but you can force a particular encoding
+     * to be returned, by setting this to 'gzip' or '' (no encoding)
+     * 
+     * 'encodeLevel' : level of encoding compression (0 to 9, default 9)
+     * 
+     * 'contentTypeCharset' : appended to the Content-Type header sent. Set to a falsey
+     * value to remove. (default 'utf-8')  
+     * 
+     * 'maxAge' : set this to the number of seconds the client should use its cache
+     * before revalidating with the server. This sets Cache-Control: max-age and the
+     * Expires header. Unlike the old 'setExpires' setting, this setting will NOT
+     * prevent conditional GETs. Note this has nothing to do with server-side caching.
+     * 
+     * 'rewriteCssUris' : If true, serve() will automatically set the 'currentDir'
+     * minifier option to enable URI rewriting in CSS files (default true)
+     * 
+     * 'bubbleCssImports' : If true, all @import declarations in combined CSS
+     * files will be move to the top. Note this may alter effective CSS values
+     * due to a change in order. (default false)
+     * 
+     * 'debug' : set to true to minify all sources with the 'Lines' controller, which
+     * eases the debugging of combined files. This also prevents 304 responses.
+     * @see Minify_Lines::minify()
+     * 
+     * 'minifiers' : to override Minify's default choice of minifier function for 
+     * a particular content-type, specify your callback under the key of the 
+     * content-type:
+     * <code>
+     * // call customCssMinifier($css) for all CSS minification
+     * $options['minifiers'][Minify::TYPE_CSS] = 'customCssMinifier';

+     * // don't minify Javascript at all
+     * $options['minifiers'][Minify::TYPE_JS] = '';
+     * </code>
+     * 
+     * 'minifierOptions' : to send options to the minifier function, specify your options
+     * under the key of the content-type. E.g. To send the CSS minifier an option: 
+     * <code>
+     * // give CSS minifier array('optionName' => 'optionValue') as 2nd argument 
+     * $options['minifierOptions'][Minify::TYPE_CSS]['optionName'] = 'optionValue';
+     * </code>
+     * 
+     * 'contentType' : (optional) this is only needed if your file extension is not 
+     * js/css/html. The given content-type will be sent regardless of source file
+     * extension, so this should not be used in a Groups config with other
+     * Javascript/CSS files.
+     * 
+     * Any controller options are documented in that controller's setupSources() method.
+     *
