BulletSim: set material properties for static objects. Move Linkset.MakeStatic() after call to ForceActivationState2() since linkset might change activation state. Make BSPrim.CreateGeomAndObject public as linkset rebuilding might need access to it. Only rebuild prim if selection state is actually changes -- OpenSimulator calls PhysObject.Selected() multiple times whenever a prim is selected or deselected.
