Title: Don't add anything to $rootScope by default; export the changeLanguage function

cc @jrencz. I wanted to stop adding stuff to the `$rootScope` by default as that's not the bes practice. Also, the function to change the locale doesn't need to be attached to anything by default; I changed it to be exported instead.
