Emitters can now damage and eventually break walls
Emitters can now completely destroy doors, given enough time.

Amount of shots per door varies depending on type. Regular airlocks are quite weak. Secure bolt-when-destroyed airlocks can take some punishment, and blast doors will take serious bombardment to destroy.
Fixes blast doors losing icon when being hit by emitter or similar weapon.
