Add Event Listener structure

[tbk303]

We need an Event Listener structure, that allows plugins to register for certain events like dispatched commands or start/exit of HenPlus.

Alright. The first event listener is available. An ExecutionListener can be added to the CommandDispatcher. It is now used in EchoCommandProperty that uses it to write out commands when this property is changed to 'true'.

I'll leave this bug open, since other listeners need to be added..
