Fix stupidity in the rotate ops; first of all it was saving the

axis of rotation numerically, so that the associative thing breaks,
and then it also wasn't saving the point on the axis in the file,
so that snapped back to (0, 0, 0) on reload. Now it goes off the
hEntity for a point on the axis and a vector in its direction.
