grab animation work

Browse source 
Hand animations now have 5 states:

* idle
* open
* grasp
* point
* farGrasp

The handControllerGrab.js script now chooses one of these five animations, based on the state of the HandController object.

Also, removed hand trigger AnimVar setting from C++ Rig class.
