As the title says. If an atom is inside another atom, which may be inside another atom that is on a turf, it should be able to recursively find the top atom right before the turf so that the audio can be heard and tracked even if it's not directly on the turf.

This would give more flexibility, you could make it a flag as well, if someone might not desire this behaviour. Otherwise, sound.atom is inoperable if you have an inventory system where sounds can be played on items within containers that exist on turfs, since they won't play properly until placed in the game world.
