Updated Aura.Router to the latest version.
Add some documentation PHPDoc to the App class.
Lazy-load global view helpers.
The router is now treated as a helper.
Update to the latest version of the Aura Router module.

The updated version contains an improvement by yours truly that makes
the Router object remember which route was matched. This allows you to
check to see if a route is the currently matched route.
Made the links in the navbar configurable.

This still needs a lot of work, but basically you define names, labels
and routes in menus.json and they appear in the navbar.

Currently custom links (non-route links) and dropdown menus are not
supported.
