About The Pull Request

Partial port of DaedalusDock/daedalusdock#996

• Fixes ambience prefrence inconsistancy issues with Observers unable to turn off the ambience buzz.
• Ambience buzz requires a working, existing, charged APC with power to the enviorment.
• Moves update_ambience_area() and refresh_looping_ambience() into code\controllers\subsystem\ambience.dm for better organization.

Why It's Good For The Game

Mostly to tackle a prefrence bug where ghosts are unable to turn off ambience buzz. But this also includes ambience buzz requiring a powered area. Makes the station feel more dead when there's no enviorment power. There should also be no buzzing inside space.

Changelog
