Patch 10 - Big rig update!

GIANT rework of wing behavior. Various rough edges smoothed down. Headpuppet has been changed for both winged (combo constraint and head-vs-chest-angle animated; SORRY IT FAILS TO SOLVE IF YOU POINT YOUR ARM TOO FAR BACK) and wingless (less weird, more stable, still pretty weird) variants. No more butt scooting (if you're in Dynamic Sit, locomotion will make you pop out of it until you stop moving again). OpenFlight body posture blendtree has been slightly adjusted to be smoother. MMD dances have a unique wing behavior to tone down the hand rotation constraint by half (it looks pretty cool dancing with them just toggled Folded, though). 

Watch out with small players and the "nose chair." You'll only safely balance others on the tip of your beak if they're big enough not to fit in your mouth...
