Show down queues in "rabbitmqctl list_queues"
Merge in default
Emit a final event to say we crashed.
Add crashed queues to the output of "rabbitmqctl list_queues". This is rather fiddly since we need to distinguish between queues which are crashed and those which are deleted in between us checking Mnesia and calling the queue pid. We do this by observing that the deleting queue removes its own Mnesia record, so we can check again and if the record is still there after the pid is down, it must have crashed. But this is still rather fiddly; and I wonder if reifying the crashedness in Mnesia would be cleaner.

Delete a bit of complicated code.
