Enhancement: Read data from package.json and set to title

It would be super cool if groc were to read the projects version + name, from the package.json file in a node.js-project and append the version & name to the browser stitle. That way one could be sure that one isn't viewing outdated docs.

Have a look at this pull-request: #98 … it's not exactly what you're looking for, but an adequate step into this direction.
