Buffs the siege crossbow

Still nontrivial amounts of recoil & dispersion, but at high skill you
can now one-shot zeds using metal bolts.
Nukes some whitespace.

Cold drinks!

This PR gives minifriges the ability to chill certain foods (primarily
beverages) and give them the (cold) flag which improves their morale
boost by 50% - or gives them a small morale boost if they have a
negative morale value.
The cold flag wears off with time (about an hour out of the fridge) and
is tied to a new comestible flag ("EATEN_COLD") with all the relevant
morale calculations taken care of in player.cpp.
DERP
Whitespace killa!

Fixes bugs in the PR.

Now to see about the extant bug - namely that comestibles in containers
hold their (hot) or (cold) status forever when left lying on the ground
and only properly lose it over time when carried.
Boarded up (reinforced) doors no longer turn into damaged doors once
un-boarded up. Also disabled the ability boarding up locked/alarmed
doors, since it unlocks and unalarms them (which obviously shouldn't
happen).
Makes fireplaces smashable.
