Implemented "sound triggers" so that the music does not stop shortly after

entering the castle. I hope this is a fair approximation of how the original
worked. Of course, this led to a couple of more renamings:

_unk5              -> _soundTrigger
updateCallback54() -> update_setSoundTrigger()
snd_setUnk5()      -> snd_getSoundTrigger()      (yes, "get")

At the moment, the only known sound triggers are the ones in the castle. If an
unknown trigger is set, the debugging messages will be really, really noisy. I
don't know if I should consider this a bug or an extremely annoying feature.
