Fix Handlebars syntax errors in Node.js page
Add routes for docs pages

This adds routes for the docs pages that seem like complete pages. The `isoporphic.hbs` does not have a route because it didn't seem like it was suppose to be a complete, stand-alone page (maybe it's a partial?).

The follow routes were added:

* `/browser/`
* `/node/`
Move Quickstart pages under "/quickstart/"
Merge pull request #7 from ericf/docs-site
