If a connection to an IPv6 network and it fails, then on the next attempt try to connect to an IPv4 address instead. Bug: #574

If the mqtt host resolves to both IPv6 and IPv4 addresses, and there is a routing issue over IPv6, mqtt should fall back to IPv4. See http://dev.eclipse.org/mhonarc/lists/mosquitto-dev/msg01633.html for more details.
