Subject: #1968 - Improve album cover generation/removal/etc. - Added stanza to
 Item_Model::save that handles when cover id is null. - Added logic to
 graphics::generate to copy/convert album cover thumbs from their item thumbs
 to ensure they're always jpg, and eliminate the possibility that we
 copy/convert a dirty thumb. - Redirected other places in code where we want
 to do one of the above two things to use these two functions instead
 (gallery_event::item_updated_data_file, item::make_album_cover,
 item::remove_album_cover). - Improved validation in Item_Model so only albums
 can have covers and all covers must be non-albums. - Added unit tests to
 Graphics_Helper_Test.
