Implement powersink surge (#2452)
Implements suggestion https://forums.aurorastation.org/viewtopic.php?f=21&p=78011 in the following fashion: Powersinks explode ~18 minutes after being placed on normal SMES setup. Obviously more input from engineering will make this process go faster. Upon reaching their capacity, they will now cause a larger area power surge. The surge will smash all lights belonging to APCs within close to moderate proximity, and call EMP act on all connected powernet items that are within range (severity depending on distance). All of those items have a small chance to cause a minor explosion as well, primarily because EMP act is fucking whimpy.
