03. Adding a bundle that will hold our application

This creates a basic bundle as produced by `app/console generate:bundle --namespace=Dbu/ConferenceBundle`. We load that bundle and configure the default template for SimpleCms Pages.

Additionally, we add a Doctrine fixtures file to load a couple of SimpleCms Pages. To load the fixtures, run

    app/console doctrine:phpcr:fixtures:load

After the fixtures have been loaded, the URL for the homepage will give you a page, as will the URLs http://conf.lo/app_dev.php/schedule and http://conf.lo/app_dev.php/speakers .
