A fix and a tweak

[getcetc]

Hair.lua: X and 0 or 1 always returned 1 before, resulting in only frame 1's getting used. "Gravity" while standing was definitively above 5, going below 5 only in couple ticks of weightlessness after reaching the peak of flight of the related actor, by which point ponytail would be behind the actor 100% of the times, rendering all this pointless, and the bob I just found looked better with 8 in place of 5.

Medikit changes: Used to heal ~36 points a use for light browncoats and ronin infantry, were absolutely useless at stopping bleeding I doubted wound-closing was implemented for them. It now heals 21 a use for browncoats, 22 for ronin infantry and 26 for dummies, and now (almost) stops really severe bleeding in two uses. I feel that this is a much better dynamic for this kind of item.

Closing this PR cause it's not needed.

• The hair thing is actually a misunderstanding and is correct as-is. Frame 0 is supposed to be the default state, while frame 1 is used when in midair and gravity is "cancelled out" by downwards motion.

• The medikit stuff has been tweaked in another branch (in slightly different ways).
