v0.4.0

• NEW: When tagging a service as Event Listener, it is possible to specify that it will only be triggered for a specific queue
• NEW: A new service is made available, commented out, in services.yml, which can be used to requeue console-command messages when their execution fails. This can be use as a substitute for the NACK feature of some queueing systems, which is not supported by the library
• CHANGED: The interfaces ConsumerInterface and MessageInterface have acquired a new method each. If you have implemented a driver you will need to adapt your code.
• FIXED: the Monitor event listener does not dump twice any more the received messages nor strip html tags
