* remove EntityItem::_simulationState (only useful to EntitySimulation) * move code from SimpleEntitySimuation to EntitySimulation * EntitySimulation now maintans many QSets of entities * cleanup and clarify use of EnityTree::updateEntity() * reduced cost of polling for entity expiries * changed "UpdateFlags" to "DirtyFlags" and clarified what they're for
