Subject: Add generic EventManager.OnObjectAddedToScene and get PrimCountModule
 to listen for that rather than EventManager.OnParcelPrimCountAdd

OnParcelPrimCountAdd had the wrong semantics for the PrimCountModule - it was invoked for every entity in the scene, not just new ones, which would screw up the untainted count.
Extend automated test for this scenario.
