Moves hot/cold checks to the fire locks
Makes detection due to above only close the affected Fire Lock and its neighbors (via merge code stolen from tanks)
Fire Alarms still can lock an area down if clicked by a user, right clicking is now the reset function. Resetting also resets all Fire Locks closed by their own detection.
Gives Fire Locks an overlay of lights that display the reason it closed (Orange for Hot, Cyan for Cold, White for unknown/Fire Alarm Pulled)
Emagging a Fire Alarm now emags all Fire Locks in the area, which accomplishes the same effect as before (disables atmos monitoring). Pulling a Fire Alarm will make emagged Fire Locks in the area display a corrupted warning light pattern, making finding and replacing emagged Fire Locks somewhat easier.
Silicons can disable atmos sensors in an area by CTRL-Clicking a Fire Alarm, much like before. but now the Fire Alarms in the area will change their sprite to hint at this (the normally-green light will turn off).
Makes a breach or fire not cause Fire Lock Hell anymore. Only the Fire Locks facing an issue will tend to close, leaving the rest of the area mostly unaffected.
This needs some work done to make it detect based on edges, but it's a decent enough start to live with if we're all killed by meteors (Lemon)
