* Combat Mechs Can Punch More Things
Removes the var to check for the 5 things it can attack, instead it can punch anything (but not everything will take damage).
Gives punching objects a check so you don't accidently smash something without meaning to.
Gives closets and canisters a proc to take_damage so they'll actually get smashed by the mechs.
* Take_Damage Boogaloo
* More take_damage Stuff
Adds click delay on attacking barriers.
Proper noises when attacking material doors and barricades.
More stuff can be broken by mech punch and simple mobs.
* Adds changelong
* usr to user
