Send Message, pass ID

[Soloam]

It would be nice to, in the send function, that we could pass a extra value after the ack request, that value would be a numeric value that the gw would return back when replying with the ack. That way we could pass a unique id with the message, allowing to filter if the messages that we are acknowledging is the expected one.

id++;
send(msg2.set(state?false:true), true,id);

something like this.
