feat(docs): use html5 history api for all routing in the docs app

- Configure our docs app to use new $location with html5 history api!

- Update simple node web server to serve index.html for all links
  (rewritting).

- Update .htaccess file to serve index.html for all links (rewritting).

- At runtime determine the base href path and attach it to the DOM. We
  needed the absolute URL to get all browsers to work well.

- Because of the above, we also need to dynamically determine all needed
  js/css resources and add them to the DOM. This was needed because FF6
  would eagerly fetch resources with wrong URL since the base element is
  added to the dom at runtime.

- All content html files were moved to the partials directory, because
  with the new html5 urls it was impossible to tell if request for
  http://domain/api/angular.filter.html was an html5 url for the html
  filter doc page, or an xhr/appcache request for the content html file
  for the html filter.
