Fix: correctly describing Quaternion.normalize()
The original comment seems to suggest that only the rotation vector
is normalized, leaving the rotation angle alone. This is not what happens,
though. The new comment matches the actual implementation, and the
implementation matches what is commonly understood as quaternion
normalization.
