docs: Adds an listener for events that gets called when the event finished processing.
  <p>
  Be careful with this method, it will register the listener for ALL the informations found in the Event. If your
  event-type is a common event type, it will fire EACH time!.
  It will also register for all Descriptors individually!
  It will also ignore if this listener is already listening to an Event.
  Method is thread-safe.
  </p>
  @param event the Event to listen to (it will listen to all descriptors individually!)
  @param eventListener the ActivatorEventListener-interface for receiving activator events
