It seems that BGMDriver was failing to compile on case-sensitive file systems because BGM_Types.h included "AudioServerPlugin.h" instead of "AudioServerPlugIn.h". (Lowercase "i".) I tried building with the project and Xcode on a case-sensitive disk image and it would fail without this patch. So I figure it should at least build now. I haven't had time to test Background Music on a system running on a case-insensitive file system yet, so I added a TODO about it in TODO.md. Also, some unrelated tidying up.
