Title: added hostname option for grunt server

I am running reveal.js in a Vagrant box. By just calling `grunt serve` it's not possible to access the server from the host, only localhost connections are successful.
In order to be able to access from "everywhere", I needed a new hostname option in the Grunt configuration which is then forwarded to the `grunt-connect module (same workflow like the `port` option).
