Should fix the Z-9's.
Almost forgot.
Mtype modified.
Another one?
Fiddled even more
More rarer harness.
Merge pull request #4802 from RadaRadaRada/dogfix

Makes the Z-9 to actually drop the harnesses and not freeze your game.
Huge damage/armor rework

* creatures now handle incoming attacks in deal_damage and take damage in apply_damage
* damage can be of multiple types, all of which can be handled differently, separately
* Creature::hit is now a shim for deal_damage, use deal_damage in all future
interactions
* added game::creature_at which is functionally identical to mon_at but returns a creature
