Function for album cleanup

1. When deleting albums with the 'Delete Songs on Album Delete' checkbox
checked, the songs are deleted but the folder isn't. We can't just blindly
delete the folder that the songs were in because there could be other songs
in the folder that weren't part of the album.  Solution: Make a tool that
searches the player for empty folders and deletes them.

2. It might also be useful to have a tool that searches for orphaned songs,
(i.e. songs that are on the player but not part of an album) and delete
them. This might help avoid situations where songs from that album are
inside an album on the player and others are not, thereby causing album art
to be displayed on some songs but not others.
