Arduino Yun + Bonjour Service Discovery

gistfile1.ino

/*********************
Elroy Service. Basic.

We'll be discovering where this is on the network with bonjour/mdns.
Then we'll interact with it.

Posting to the /on endpoint will turn pin 13 on.
Posting to the /off endpoint or any other endpoint will turn pin 13 off.
