reply_to requires queue name, but used as routing key

[orlade]

TAMQOutputTransportFactory uses msg.properties['reply_to'] as a routing key for the response message, however TAMQTransport (used on the client side) populates the reply_to property with the queue kwarg. queue is required to be the name of a queue, not a routing key, and thus this pair of transports will only work if the response queue is bound to a key which is the name of a queue (typically itself).

In other words, it assumes a default exchange type, not a direct exchange, but this isn't made particularly clear (TAMQFactory even declares direct exchanges, but binds the queues to their names like a default exchange).

So this is really a request to support direct exchanges. I may add this later if it proves useful.
