[gh-417] Add media (7.x-2.0-unstable6) and file_entity (7.x-2.0-unstable6)
[gh-417] Add Media: YouTube 7.x-1.0-beta3 module
[gh-417] Initial commit of Media: Mediahub module

Will not work at this time because mediahub needs to be updated to
support getting file url through
 http://mediahub.unl.edu/media/{$variables['video_id']}/file
[gh-417] Fix mediahub theme file

Use the real file path if we can grab the json, otherwise rely on /file and
use video/mp4 as the type which seems to work with any video type.
Only output the track element if it exists.
[gh-417] Comments for mediahub theme
[gh-417] Add support for audio play to media: mediahub
[gh-417] Add Media button to UNL's WYSIWYG button order
[gh-417] Set Media settings in Media: Mediahub install
[gh-417] Disable access to Content->Files tab and Media settings

We don't want anyone touching the settings, they can be managed if need be
in the hook_update process.  The Files tab showing Media just will cause
confusion for now.  The point of this module is to enable a simple
WYSIWYG button to add videos, as the Media project matures utilizing more
of it can be considered.
