Patch 9 - BANKING IN FLIGHT update!!!

BIG THANKS to Purpzie for recommending I add banking in flight--because I added banking in flight (well, in Open Flight)!

Additionally, I reworked the wingless version out of a fresh copy of the winged one, so that it wouldn't have mystery problems. The wingless gryphon now has the correct head posture in flight!

Collider flight has been returned to its original/intended hitch style, so now its motion is strafing. Only Open Flight is on the physics hitch. 

WARNING: VRChat has been digging into a constraint/physbone bug recently, and some of their fixes give this avatar whole-body jitter when you look down in VR. This is NOT my fault, and the issue has been marked Tracked in the VRC Canny. Hopefully it clears up here in a bit.
