Eric House 0e14783d3b use negotiated streamVersion to decide what to send via MQTT
No point in sending the old-topic-format MQTT messages to clients that
know about the new one, and in fact it's harmful. Devices in a game
already agree on the stream version to use and communicate it, so pass
that into comms once it's known and from there on to the device code
that builds mqtt messages.
