mathutils rotate functions for Euler/Quaternion/Matrix/Vector types.

Browse source 
each accept Euler/Quaternion/Matrix types.

eg:
  Euler.rotate(Quaternion(axis, angle))
  Vector.rotate(Euler((pi/2, 0, 0)))

matrix.resize_4x4() and euler.make_compatible() were still returning an instance of themselves, now return None.
