Second parameter for produce to allow alternate queue name

Just to sum up the things we talked about on irc.

Envelope should contain the information about the queue, preferably in the constructor.

The current Message::getQueue() guessing should be moved to utils or into the Producer.

The Seriailzers needs up be updated to allow for the queue property. We must support it being missing, so that we can still interchange messages with resque or sidekiq.

#73 is related and should make it much easier.

Since i did some major refactoring doing Middleware i have added this into the Producer.
