title: Restify won't listen on ipv6
body: <p>Using the sample server from restify's README, it starts up and binds to port 8080 on the ipv4 address only. Is there a way to get it to bind to all the addresses? Mac OS X.</p>
  
  <pre><code>$ node test.js
  myapp listening at http://0.0.0.0:8080
  
  $ netstat -an | grep 8080
  tcp4       0      0  *.8080                 *.*                    LISTEN
  </code></pre>
  
  <p>It's slightly annoying because 'localhost' tries the v6 address first, and some clients (eg: curl) do not try other addresses. I have to remember to always type 127.0.0.1 explicitly.</p>
  
  <pre><code>$ curl http://localhost:8080/
  curl: (7) Failed to connect to localhost port 8080: Connection refused
  
  $ curl http://127.0.0.1:8080/
  {"code":"ResourceNotFound","message":"/ does not exist"}
  </code></pre>
