Shotgun slugs and revolvers were pretty much stong, by instagibbing people ignoring armor, due to having a maim bonus. This pr will remove this, those weapons can still maim and gib limbs, but without any magical force that is able to ignore armor. Plasma cutter and heavy sniper bullets still keep this feature for obvious reasons.
