Subject: [PATCH] Check if file can't be loaded in SoundTrack::SoundTrack()

This adds a check that the pointer passed to
FILESYSTEM_loadFileToMemory() isn't NULL, and if it is, just returns
early in the function, instead of continuing later and producing a
different, slightly-misleading error message.
