Allows Super Admins to control which plugins are visible to admins of a given site within a multi-site WordPress environment.
Added 'Visible to Network' functionality, so that plugins can be made visible site wide (Managed through network admin plugins page). Updated interface so that plugin visibility is done purely through the plugins page. Implemented nonce.
Updated to be compatible with 3.1
Added the ability to bulk show/hide plugis only for the current site. This can be found in the Plugin Visibility Manager page in the Super Admin menu.
Original public release.
