Curve Refs qL SOP: removed from Tab menus
Superellipse qL SOP enhancements:
- interface version 2 (incompatible parameter changes)
- better parameter naming (same as Circle SOP)
- faster :) (single vop sop)
- plane precision issue addressed (hackishly, though)
Merged work:
- Superellipse qL SOP (i2)
- Curve Refs qL SOP (removed from menus)
