Essentially, "spherical" is an alias for the "floating" joint type, with no translation component in the transformation matrix (I added a check for this in Joint.get_child_poses()). This is supported by the Bullet/PyBullet physics simulator and represents joints that have free 3D rotation but fixed origin.
I took care to add comments in the right places I think.
Addresses issue #8.
