Dead Pieces

Hello everyone!

As you may know, awhile back a tragic incident occurred on this site, where many of the uploaded media has vanished from our server (this was due to a faulty script, which has now been addressed). However, there are a lot of dead pieces hanging around this place. As a courtesy, I have written a script that will warn you if you have any dead pieces lying around. A dead piece doesn't mean your actual thread has been deleted. Your threads and comments still exist, but in some cases the mp3 has been wiped from the server, and you will get a "file not found" error (or in the case of a midi file, it will take you to a blank page). When you reupload your media, your warnings up at top should disappear.

Thanks for doing this Chopin!
