Include thread related headers in issue/coment mail (#7484)

Browse source 
* Include thread related headers in issue/coment mail

Make it so mail programs will group comments from an issue into the same
thread by setting Message-ID on initial issue and then using In-Reply-To
and References headers to reference that later on.

* Add tests

* more tests

* fix typo
