06. Add a special controller for a specific page

We make the schedule page show the actual schedule. 

After switching to this branch, you need to reload the fixtures to get the route type information updated. As usual this is:

    app/console doctrine:phpcr:fixtures:load -n

We still have no menu, so to get to the schedule page, you need to enter the URL by hand: http://conf.lo/app_dev.php/schedule
