- authkey/modkey will be assigned when messages are held in auth/mod spools.
- "smtp" method (scenario returns "editor" status) no longer needs modkey or one time ticket.
- Attachmets in requests are no longer taken from files: tt2::allow_absolute_path() is no longer required.
- Use auto-generated values for message IDs and boundaries of requests.

Known bug: At once the message is held, confirmed/approved message won't be encrypted even if it was originally encrypted.
