Change to text3d: When back or front is enabled, the bevel rim on the other side is not created anymore, just as the back/front filling faces are not created when disabled.

when both are off the behavior is unchanged.

This is needed when rendering alpha text so its possible to have a single layer of faces but use the bevel option to make text thicker.
adding a rim on the back when back is disabled also doesnt make much sense IMHO.

minor python edits too.
