Adding clarification of the point of using the "app" Twig variable in…

… our project This is after some user had issues posted via comments: https://knpuniversity.com/screencast/symfony2-ep1/mind-tricks#comment-983252106 This shouldn't relate to any CSS issues, so I'm not sure what's going on with that, but hopefully this will help

 Actually, it's an object called `GlobalVariables`_, which you can check out
 yourself. So when you need one of these things, remember that app variable!
