Make the API less dumb

[hopkinsth]

Opening an issue for (eventually) making some API changes, like, for listeners...

queue.listen({ack: true}, function (msg, ack) {
    doStuff(msg);

    this.headers; //message headers
    this.info; //other delivery information

    //want to acknowledge the message? just call `ack`
    ack();

    //rejecting the message? just pass false to `ack`
    ack(false);

    //want to reject and requeue? pass true as the second param to `ack`
    ack(false, true);
})

set options with calls?

queue.listen().ack(function (msg, ack) {

});

Want to rethink some different stuff.
