[Soc-2016-dev] Weekly Report #11 - Bezier curve improvements

[Duaret Ramos Sapo]

Your curves are not corrupt, don't worry.

I hand not noticed this issue before, your operator is probably ignoring 
or not interpolating the Curve Radius property properly, leading to 
bevel and extrusion factors disappearing.

I'll post more info about this in your Blender Artists Thread
