Corrected melee crit chance calculations

Problem is described issue #4917
Restores the atomic nightlight's proper light value.

I have no idea why this was changed.
Even if it lasts forever, a single square of light is useless, and the
fact that it's a lightstrip that never runs out of power is really all
that makes this thing even remotely worth having because it weighs 8+
pounds.
HACK: Fix crafting search. Not the best way to do it, but it works for now.
Removed quartering of stab damage
