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!
