Meteors and Space dust (now that they work again) will no longer have an effect on singularity containment. Field generators and Emitters are protected.

I added a check to meteor and space dust Bump() directly because changing ex_act() on the machines themselves would make the machines immune to bombs and C4.
Hopefully fixes issue 716.

light/process() was added back in causing lights to use power as they were meant to. Recently lights have been made brighter causing more power to be drained. As a result the engineering APC would not last very long. The station using a lot of power is a good thing since the singularity produces an incredible amount of power, so to keep this higher power demand but still give engineers a fighting chance to set up the singularity, I've bumped up the engineering APC's starting battery power.
