add a create-flag to the node() method of a PropertyObject, defaulting to false to maintain existing behaviour. This could be used to add a listener to a non-existing property without having to write a dummy-value beforehand. Usage: myPropertyObject->node() returns the corresponding node or NULL if does not exist or has not been accessed before. myPropertyObject->node(true) returns the corresponding node, never NULL. If the property does not exist, it will gets created.
