+ * Perform an action via ajax

+ * <pre>

+ * elgg.action('name/of/action');

+ * </pre>

+ * Note that it will *not* love you if you specify the full url as the action

+ * (i.e. elgg.yoursite.com/action/name/of/action), but why would you want to do

+ * that anyway, when you can just specify the action name?

+ * 

+ * @example Usage 2:

+ * If you want to pass some data along with it, use the second parameter

+ * <pre>

+ * elgg.action('friend/add', { friend: some_guid });

+ * </pre>

+ * 

+ * @example Usage 3:

+ * Of course, you will have no control over what happens when the request

+ * completes if you do it like that, so there's also the most verbose method

+ * <pre>

+ * elgg.action('friend/add', {

+ *     data: {

+ *         friend: some_guid

+ *     },

+ *     success: function(json) {

+ *         //do something

+ *     },

+ * }

+ * </pre>

+ * You can pass any of your favorite $.ajax arguments into this second parameter.

+ * 

+ * Note: If you intend to use the second field in the "verbose" way, you must

+ * specify a callback method or the data parameter.  If you do not, elgg.action

+ * will think you mean to send the second parameter as data.
