First pass at moving polystrips panels and preferences to the UI file. Currently fails.
bug fix
Rename Contours Retopology panel to just Contours
Swap UV Sphere icon to Bezier Curve on Polystrips for now. Later to be replaced with custom icon once supported.
Rename Polystrips Retopology panel to just Polystrips
Merge branch 'feature/jd_polystrips' into feature/polystrips_ui
Remove box from panel layout. This just adds clutter and is no longer needed.
Use the IPO_BEZIER icon for Polystrips instead. It's sexier.
Move Contour button above box, keeping settings that belong to Contours in the box.
