Add logging of events that flow through event bus.

[Unisay]

Its not a bug but rather a feature request:
Event bus makes it harder to debug program. Having ability to switch logging on would greatly simplify life. It would be really nice to see events in the log as they are fired and consumed.

You could create a subclass of SimpleEventBus and override the fire(...) and on(...) methods. In both methods make a call to super and do the logging. Then instead of creating an instance of SimpleEventBus or calling the factory constructor in EventBus (which also creates a SimpleEventBus), create an instance of your new logging event bus.

Let me know if it works.

I've added a class LoggingEventBus and an additional name attribute to EventType for logging.

If you instantiate LoggingEventBus and provide the additional name to your EventTypes the events are all logged (see also the example).

Thank you Marco!
