Media Folder Reorg

This looks like a massive PR but it isn't really.  Removed some useless files, moved some libs to more appropriate places, etc.  Here's the breakdown:

1.  Removed a bunch of useless JS files.
2.  Moved CKEditor to "js/libs"
3.  Moved ACE to "js/libs"
4.  Moved Font Awesome to "css/libs"
5.  Moved Prism to "js/libs"
6.  A few updates to templates with updated paths

There will be a bit more to do, as I'm sure we can update a few jQuery UI plugins and cull some CSS files, but this is a good start.
