AttachFile: add ticketing for all operations that do modifications Tickets for upload (POST), also for every (GET) URL except do=get and do=view. Avoid KeyError if there is no ticket (was a minor issues, because there has to be one). Use the same i18n string for all "Please use the interactive user interface" messages.
