Add option for muting music in Bowling Alley and Shaktool's Room

[CPColin]

Betus and Pink tend to play their own songs during the slow parts in Bowling Alley and Shaktool's Room. It might be nice to have an option where those rooms mute the music when the player enters. Look into how the music track is selected. I think it's by door, suggesting the following:

• Bowling Alley music should only mute when entered from West Ocean and should unmute when exiting from either door
• Shaktool's Room music should mute when entered from East Pants Room, should stay muted through Spring Ball Room, and should unmute when reentering Shaktool's Room

This option should be off by default.
