Fix Plane move and add moved

[MatthiasJ1]

Plane.move contradicts the documentation on move vs moved (here) and is missing moved, therefore operations like Pos() * Plane will fail.

Thank you! The test for Plane.move isn't complete:

    def test_move(self):
        pln = Plane.XY.move(Location((1, 2, 3)))
        self.assertVectorAlmostEquals(pln.origin, (1, 2, 3), 5)

Would you correct this test by checking that the instance of the Plane hasn't changed and introduce a new test for moved that checks that the instances are different?
