emails: fix one-click unsubscription.

Fix it so that emails are (hopefully) able to show the one-click
unsubscribe button in Gmail and other mail providers that support the
List-Unsubscribe header. This way users can unsubscribe instead of
marking emails as spam.

* Add the List-Unsubscribe-Post header.
* Fix the disable email notifications endpoint to support POST as well as DELETE requests.
* Fix the disable email notifications endpoint to disable XSRF protection (we don't need
  users to be logged in because we use a signed URL instead).
