Patch submitted, part1:
- reworks conetwist decomposition geometry
- modifies viz for conetwist
- adds motorization (for obsolete version)
- adds damping (for obsolete version)
- reworks limit softness (for obsolete version)
- added ConeTwistConstraintDemo to demo motorization. (please add it to the 
solution
by hand. when i do it in visual studio, it messes too much with the .sln file.)
- little fix for picking and body sleeping in demo framework

notes:
- conetwist constraint is set to use obsolete version by default. (for ease of
testing. feel free to change this.)
- check the viz in the ConstraintDemo
- check the ConeTwistConstraintDemo

Overall, this should be a "stable" patch, but there's more to come. Including
motorization and more for the non-obsolete version.
