Fallback to the defaultlocale

The problem is that when you run the BundleGenerator it installs a simple DefaultController with a template. When you run the DefaultSite generator it only enables the site on the /en URL. Everything else still simply shows the DefaultController's action.

So I removed the action in the DefaultController, added a listener which detects failed responses on the root URL which redirects to the root URL for the default locale.
