Subject: * Tweaks physics so that linked prim are a single body.  This will
 make linked prim more stable and probably the last obstacle to vehicles
 physics wise. * Fixed a bug that caused physics proxies to be scattered when
 you link an object. * Single physical prim work exactly the same as before,
 just linked physical prim will have changed.
