Combat Mechs Can Punch More Things (#6303)

* 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
