Patch 12 - Bugfixes/polishing. Final update??

A key aim constraint in the body has been failing to solve at certain angles this whole time. I figured out how to stabilize it, and was able to remove an entire stupid subsystem I'd had to put in to try to cover up its problems. Hindbody response should be dramatically improved. 

Adjusted the neck/head angle in flight to look a bit better.

Added GoGoFly "support" to the main PCVR gryphons, but not GoGoFly itself (if you add GoGoFly, the gryphon will properly enter its custom flight mode when Go/Fly or Go/Dashing are TRUE). 

Fixed the seams in the baked bangle illumination.

Probably some other stuff..,
