Can no longer use fire extinguisher closet without hands

If you did not have hands,you could click on a emergency closet and have a fire extinguisher spawn in your hand,and you could either put it back and not abuse the oversight, or use it like people with hands.
Cool,right?

Edit: I hope you don't mind if I fix some other .dm's like the fire extinguisher. It's one less PR; one more commit to patch 2.
