setlang will now display a dialog to confirm with the user that they would like to change their interface language. The preferred language will only be updated if the user confirms. The dialog will be displayed if the setlang parameter is present in the query string and, * A user is logged in, and their preferred language is not the same as the one passed via setlang. * For an anonymous user if the wgULSAnonCanChangeLanguage is true, and the current interface language is not the same as the one passed via setlang.
