(svn r5669) - Backport from trunk (r5464, r3641):
Codechange: verify the presence of music files in the gm folder. Slightly altered r5464
to exclude the addition of music.c and left out the extra functionality. While in essence
this is not a true fix, several people have reported a rising CPU usage because Dmusic
kept indefinitely looping the file list. This should solve that.
