Motivation
Even though the FileExporter already checks the permission rights of the user, we want to make sure that the FileImporter only allows users with enough rights independent of where they come from.
Task
Before loading and after saving the FileExporter specialPage, check if the user is at least autoconfirmed. If they are not logged in, allow them to log in before being redirected to the specialPage. If they don't have enough rights, give them that error message.
