New Webpage

IDA changed webpage by 2019-02. some of the documents (Application, earlier Reports), aren't moved / linked correctly (still by 2019-03), so one has to search via web.archive.org. I gave formatter URL (P1630) also for wayback, and new format as "preferred rank". W!B: (talk) 05:20, 28 March 2019 (UTC)
