@brief Callback for when the listener is added to a queue 

The default implementation of onAddToQueue() and onRemoveFromQueue() provide tracking of the queues this listener is added to through the #mQueues member. Overrides of onAddToQueue() or onRemoveFromQueue() should ensure they call the parent implementation in any overrides. 

@param queue The name of the queue that the listener added to @see onRemoveFromQueue()
