When slaughtering a domestic animal it should be insta-kill.
It was changed from instakill in rP12792 (female citizens) and rP13400 (cavalry and infantry) but I do not know why. If anyone has an idea on this, please enlighten me.
Part of this change is a small restructure in Attack.js.
Question: If an attack type is not known should it default to trying to do damage anyways? (As is currently.)
