Changeset 2155 for code/branches/objecthierarchy/src/core

Message:

added mbool (bool with memory) to fix particlespawner-on-client problem. maybe further changes are needed if a similar problem affects other classes.

if the mbool changes from true to false and back to true within one server tick, the value stays true on the client, but a callback is called.
if you have to switch the state also on the client, a more advanced control logic is needed, but also possible with mbool (you could use 2 mbools, synchronize one and compare with the other).
