Normalise Node rotation quaternions per the GlTF spec.

We noticed some converted files where invalid when run against the gltf-Validator. The error message:

  "code": "ROTATION_NON_UNIT",
  "message": "Rotation quaternion must be normalized."

Added a normalise function similar to gl-matrix which solves the problem.
