let gravity modifier, friction, restitution and density changes be applied

to prim. Only have efect on root prim. Density doesn't get effect
imediatly, only on next change of size or shape. density change
implies a full body rebuild to be done later, after reducing the  number
of sets sop does. Other parameters should work. **** mainly untested ***
