* Fixed bug with input devices that where added, removed then re-added.
The default mappings were being ignored on the second add.
* Fixed potential crash when hardware inputPlugin device poses were polled from the JavaScript thread
by taking the UserInputManager lock during pluginUpdate.
* Renamed Controller.Hardware.Vive.LB & RB to LeftGrip and RightGrip, to better match Oculus touch.
* Updated resource/controller/vive.json to reflect this new mapping.
* Exposed touch pad capacitive touch events to JavaScript as
Controller.Hardware.Vive.LSTouch and RSTouch.
* Added viveTouchpadTest.js script to test LSTouch and RSTouch events.
Copied the delta based computation of velocity and angularVelocity that was in
Application::setPalmData() and moved it into SixenseManager. This will guarantee
that the velocity computation is the same as it was previously. The goal here is
to NOT change the behavior of the hydra.
The moving average style calculation of velocities has been removed.
Removed dead code.
Pass a InputCalibrationData to each inputPlugin and inputDevice.
This contains the most up sensorToWorldMatrix, avatarMat and hmdSensorMatrix.
Each input plugin can use this data to transform it's poses into Avatar space
before sending it up the chain.
This fixes a bug in the handControllerGrab.js script that relied on the hand controller
rotation/positions being in the avatar frame.
