Router: bonjour/zeroconf services for OTA programming and *.local name resolution

[the-magister]

Nyctinasty_Comms library module makes OTA programming via the IDE and name resolution in *.local available via mDNS. The router is running avachi-daemon and mdns-daemon, so it should "see" the ESP8266 devices. It doesn't, and I suspect:

• Something in dd-wrt is blocking that announcement/service. I have tried turning off the firewall.
• Something in DNSmasq could be culprit for *.local lookup.

@giles7777, check the test/ directory for this simple code:

https://github.com/the-magister/nyctinasty/blob/master/test/BasicOTA/BasicOTA.ino

1. Convince yourself that this works when connecting to your home (presumably Bonjour-friendly) network.
2. Then swap to the project router, and see if it works.

If these test clean, then we're in good shape.
