keep in sync with your music collection.  What this means is that if you
should remove a song, or edit a tag such that one of the tree view categories
is empty, the category will automatically delete itself.  Also, adding tracks
or editing a new tag will automatically create the appropriate entry, even if
you've already expanded the tree view out.

This fixes a couple of bugs, and although the patch is rather large, it has been
reviewed by Scott <wheeler@kde.org>, with some of his suggestions implemented.
Of course, I would appreciate testing, I've been running it here for quite a few days.

No strings were harmed during the making of this patch. :-)
