e7991579ef Enabled elbow pole vectors 
There are still some issues with rotations of the elbow pole vectors.
* When the (hand - shoulder) vector approaches the normal vector used in Rig::calculateElbowPoleVector() unexpected twists can occur.
* Also, when the (hand - shoulder) vector approaches zero, the IK system starts to flutter between two states.
* The shoulder twist constraint probably needs to be opened up for more natural range of motion.

b68dbab994 Fix for incorrect hand offset when backing into collision. 
We know properly account for the offset of the head due to clamping from a small maxHipsOffset.
This means the hands should look more natural when you are out-of-body and are moving your hand controllers.

837b19ed1b fix for pushing avatar into floor when exiting away mode. 
* Removed MyAvatar.reset() access from JavaScript
* Added HMD.centerUI() to JavaScript, which can be used to reset the 3D UI sphere around the current HMD orientation.
* Added MyAvatar.clearIKJOintLimitHistory() which can be used to reset any remembered IK joint limit history.
* Added MyAvatar.centerBody() which can be used to instantly re-orient the avatar's so that the hips and toes
  are facing the same direction as the current HMD orientation.

away.js now uses the above new API's instead of MyAvatar.reset()
