Log Message:
-----------
Povray
* Sun lamp type export (known as parallel lights in povray)
* Native support for blenders metaballs, currently exports
- ball and ellipsoid types
- radius, stiffness
- ellipsoid xyz scale
- negative elements
- single material (like blender)
Renamed rna props.
elem.sizex -> size_x
mball.last_selected_element -> mball.active_element
minor changes to UI scripts.
