new trait: "supreme pain tolerance"

[KikiMofo]

Who would WILLINGLY give away their ability to scream? Seems like a horrible thing. For me at least.
Painblindness is an interesting idea for a trait though. Like those stories of kids you'd hear putting their hand on a hot stove and their mothers seeing and yelling to take it off because the kid didn't know any better because they couldn't feel the pain.
I dunno how you'd be able to add that into the game without it being too strong however.
