Moved/renamed/deleted files, location field, and lost Library info

Songbird is definitely my favorite media application. But let's face it: Keeping files organized when it's trying to keep track of them in the Library is a pain.

I have a sort of rule within my music folder that, if I get more than a few tracks by an artist, I give that artist a subfolder. Unfortunately, that means Songbird loses the file and I have to delete and re-import that track. It wouldn't be such a big deal if I didn't lose all my ratings, play counts, and so on.

Also, sometimes I rename files. Songbird loses those too. Same problems.

So Songbird needs to be able to 1) detect that a file is missing and 2) prompt the user to find it or delete the Library entry.

I would also find it useful to be able to search on the file location field and edit that field preemptively when I move or rename something.
