Make bind host configurable

[mcasimir]

Looking at the sources I couldn't figure out how to make console.io server bound to 0.0.0.0 instead of localhost. This prevents me to access console.io server from other devices that my laptop in my local network.

Thank you!

You should be able to access console.io using your ip address instead of localhost.

I've to try this yet, anyway unless express.js does something by itself it should not be always true.
