Merge pull request #4919 from ianestrachan/fix-armor-absorb

Fix some aspects of armor absorption.
More traits

Wasted the night trying to get non-retractable claws to mean something.
At this point, the difference is cosmetic.

The Paws prereqs are OR'd, as I understand JSON protocol.
Corrected melee crit chance calculations

Problem is described issue #4917
Restores the atomic nightlight's proper light value.

I have no idea why this was changed.
Even if it lasts forever, a single square of light is useless, and the
fact that it's a lightstrip that never runs out of power is really all
that makes this thing even remotely worth having because it weighs 8+
pounds.
HACK: Fix crafting search. Not the best way to do it, but it works for now.
Removed quartering of stab damage

Traits, 3 (NEW TRAIT YAY)

All you grouchy people who think there's too much Fun in the game? I
give you BAD TEMPER.  All the morale effects of Optimist... BUT IN
REVERSE!  D:

And bears, lizards, and Chimeras can get it.  Cancels Optimist too. D8

Also gives bears High Night Vision, as promised, and cleans up some
problems, chief among them that Paws was kinda wimpy.  Now it gives -1
to craft checks that use electronics, mechanics, or tailoring.

All we need now is to get Hibernation properly prepped and get
Inconveniently Large in, and this'll be ready to go!
player no longer has stat variables which shadow the Creature versions
use fire-charges when actually cauterizing, not before
prevent candles and flammable arrows disappear
Recolored zombies
