* Playlists are treated similar to directories in the browser, they now open in the viewer when selected instead of automatically starting the playlist.
* Make the "Playlists" main menu item useful, it now displays the playlist catalog (and has been renamed accordingly)
* Default to storing playlists in the catalog
* Add a UI to move the catalog directory
(other minor stuff too)
