Should use localPosition to support moving of the Rig

[djzielin]

The hands aren't under the rig if we move the rig. Need to set hand position using local position to get this to work.

WebVRController (line 210 and 211) should be
transform.localRotation = rotation;
transform.localPosition = position;

also 289 and 290.

I just ran into this issue as well. Thanks for the proposed fix, and also @caseyyee 's branch with more lines on which the fix must be applied.
