(In [svn:9022]) 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.

(In [svn:9044]) Refs #3236 cleaned up the widget css in admin area

[cash]

(In [svn:9045]) Refs #3236 removed elgg-states-* from admin css since it was overaggressive

[cash]

(In [svn:9047]) Refs #3236 updated the button css so that disable plugin button looks like a button

[cash]

(In [svn:9110]) Refs #3236 added some margin to the bottom of the admin footer

[cash]

There are about 120 lines that still need to be updated (section: ADMIN MISC). Example:

.plugin_settings {
	font-weight: normal;
}

[cash]

The admin theme also needs section headers in a few places

buttons have too much margin

[brettp]

It's functional but not perfect, so I'm pushing out to 1.8.1b. No one should be modifying the admin theme, so we can make minor without worrying too much.

I'm leaving buttons/input review for ticket #3809
