Listening on property changes

You can listen on added properties, changed properties or on removed properties, the following code snippet shows how to do it:
```
 I_PropertyChangeListener ll = prop.addPropertyChangeListener(theKey, new I_PropertyChangeListener() { public void propertyChanged(PropertyChangeEvent ev) { System.out.println("propertyChanged: " + ev.toString()); // key = ev.getKey(); // old = ev.getOldValue(); // value = ev.getNewValue(); } } ); 
```
Note that setting a property with an equal value is not triggering an event.
