From 113b813b5a5ec8b93ee72d4f259d8e38f9a9c5e4 Mon Sep 17 00:00:00 2001
From: brettp <brettp@36083f99-b078-4883-b0ff-0f9b5a30f544>
Date: Mon, 25 Apr 2011 18:12:10 +0000
Subject: Fixes #2899, #2870. Added README.txt, CHANGES.txt, COPYRIGHT.txt,
 LICENSE.txt, and INSTALL.txt as markdown files for plugins. Added page
 handler to parse and serve them. Added links in plugin admin. Refs #3236.
 Problems with displaying parsed markdown because of missing parts of the
 admin theme's CSS.
