Fixed a backwards subsystem...

Sigh. The Hips Reverse Roll gait fix has been half-strength and backwards this entire time (subtly making the avatar worse, when engaged). Fixed. 

Also fixed some other stuff, now that I have FBT set up again. You should now be able to properly get down, wave your legs around, and even roll over, the way I've been claiming you could this entire time. >.>;;;
