Moved all animation control out of the handControllerGrab.js script and back into
squeezeHands.js
Deleted old hydra/squeezeHands.js to avoid confusion.
Added new sqeezeHands.js script to the default scripts.
* Account for controller dead spot. This helps us to see first few frames of the opening animation
and the last few frames of the closing animation
* Added a small amount of smoothing on the triggers
* Fixed bug when controllers were closed quickly and the animation frame was never getting set,
because frame and lastFrame were equal.
* Changed animation urls to Ozan's latest.
