Unarmed weapons + stabbing + claw mutations

In current version of the game, unarmed weapons can't stab at all (punch dagger will only cut), but get bonus claw damage when used by clawed mutants without gloves.

This makes it so that claws don't give any bonus when using unarmed weapons and allows unarmed weapons to stab.

This is a nerf to claws which kinda suck already, but I think it was the intended behavior so I went with it.
Possible improvement would be to add claw damage on top of weapon damage or maybe only when the weapon doesn't have this type of damage. This would make claws slightly less bad, though it would also be less realistic and intuitive.
The CQB bionic isn't designed to handle mutations and largely takes over your motor functions whilst active.  (You think "attack" and it puts you through the motions; that's how the bionic operators can still use their slam.)  This should only apply when unarmed or using a bionic weapon.
