[kepler-dev] debuging in actor development

The "listen to actor" action creates a debug listener window (see 
ptolemy.actor.gui.DebugListenerTableau), which will show any debug 
messages written by the object via the _debug call. Although the 
approach is certainly similar (observer pattern), in our case we need to 
observe other events (eg., tokens being sent/gotten, status of workflow 
execution, etc.) in a similar way as the provenance framework does. We 
are now determining a set of events (and corresponding listener 
interfaces) that will be particularly relevant for the monitoring icons.
