The Hibernator

Still needs the food/fatigue connection, but heavier-duty sleep is in.
Hibernator 2: Sleeping Day

OK, the numbers'll probably need some balancing and the code doesn't
want to let me break out additional levels of hunger/quench.  But the
mechanics appear to be working.  Commit time.
trait-picker, 1

Starts fleshing out the category some.  Ear evidence is inconclusive so
bear ears aren't as good as canine ears.
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.
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!
Hibernation & Large OK

Hibernation is now working within acceptable parameters and
Inconveniently Large is effective.  I'll commit the mutagens, recipes,
spawns, and dreams shortly.
Infrastructure files

Made another tweak to hibernation's burn-rate too, but this should be
everything needed to bring it into mainline.

Bad Temper could use another trait in the line (upgrade to Berserk, per
NaturesWitness) but I'd like to get this cleared and merged before it
gets any more out-of-makefile.  Can make that trait later.
Hibernation safety-catch, burn-rate tweak

Installed a safety to kick out of Hibernation's slow-sleep in case of
Very Thirsty, and turned the burn rate up a notch.
Y/N prompt cleanup

Makes my locking out the alarm look a little nicer.

(Seriously, all it does is create noise 36 for the whole time.)
