[PATCH 1/2] emacs: Add a fake Tags: header during display.

If `truncate-lines' is `nil' in `notmuch-show-mode' the tags can be
lost from the right edge of the window. Create a fake 'Tags' header to
display them with the other headers.
Enable it by default by adding it to `notmuch-message-headers' and
keep it up to date during tagging operations.
