* Valid Sculpted prim now collide properly.

* The first time you set the sculpted texture of a prim you might have to futz with it to get it to generate a sculpted physics proxy
* Note that there are already issues in Trunk, (such as the prim scaling issue and prim jumping issue.  Essentially editing is difficult right now)
* This just adds to the experimental nature of trunk. :D
