Prevent Trolls from damaging you and your factory

A very simple mod to prevent guns and vehicles from being loaded with ammo and prevent grenades and poison capsules from exploding and doing damage. Trolls can still make the grenades, but get no satisfaction from tossing them around. You'll have to defend yourself with other capsules and turrets, instead.
