- move versions to a tab in the files sidebar
- added mechanism to auto-update the row in the FileList whenever values
are set to the FileInfoModel given to the sidebar
- updated tags/favorite action to make use of that new mechanism
Whenever tags are updated, they need to be updated in the file list's
file info array as well.
This commit also adds unit tests and makes sure that whichever tags are
sent back by the server after update are used when updating
attributes/fileinfo.
