API v1.1 - Lazily Create Queues

Registered by Kurt Griffiths on 2014-03-10

When a message is posted to a queue that does not yet exist, create it on the fly. Also, when listing messages in a queue or claiming messages, allow the queue to not exist (conceptually, queues "always exist" and if we don't have a record for the queue, we just treat it as being "empty").

P.S. - Error codes for the transport will need to be redefined on the wiki and in docs as well. Instead of 404, you will get empty lists and such.

P.S.S. - This change may encourage app developers to no longer think about managing the lifetime of queues. As part of this blueprint, we should consider ways to mitigate (or remove altogether) the cost of unused queue resources if users don't bother to delete them.
