Patch: Code and Test


If there is no subscriber for a topic the message gets silently dropped. I suggest to add an optional default channel that receives all those messages. The default channel can then be used in scenarios, where the complete set of topics might be unknown beforehand.
This functionality resembles the 'dead letter' pattern in messaging systems.
