Minor Emitter Tweaks

Emitters no longer die by shooting a taser or laser tag gun at it.
Emitters don't explode if they are not on a powered wire with sufficient electricity in it.  They will just crumple away instead if integrity is reduced to zero.
Taking any damage to the emitter no longer results in instant death due to me being an idiot awhile ago.
Emitters can be examined to see if they are damaged, and can be repaired by applying metal sheets to it.
