* Pass 2 of collidable (non physical) linksets

* Linkset status is now persistent
* Tweaked a physics child prim positioning hack to generate less database saves
* Re-factored physics object creation calls into ApplyPhysics.  To create a new physics representation of an object or linkset, it's only necessary to call *group*.ApplyPhysics(bool m_physicalPrim).  *lbsa has been waiting for this refactoring*
* We have collidable linksets now. (they don't become phantom anymore)
