notify: add option for deterministic message-id generation

notify.domain
  Default email domain for sender or recipients with no explicit domain.
  It is also used for the domain part of the ``Message-Id`` when using
  ``notify.messageidseed``.

notify.messageidseed
  Create deterministic ``Message-Id`` headers for the mails based on the seed
  and the revision identifier of the first commit in the changeset.

  Style file to use when formatting emails.
