Laser pointers, overchargeflashes, various fixes

Alcohol and thermite now flammable.  Laser pointers added!  Flash now
comes in delicious incendiary flavor.  Robot fire overlay bug fixed-ish.
Being lit on fire turns off a borg's lights but the fire still shows.
I'll take it.  Shield gens actually useable by the people they were
meant for.
