issue2550803: Replying to NOSY mail goes to the tracker through reply-to, not original message author. Created new [tracker] replyto_address config.ini option to allow: 1) setting reply-to header to the tracker 2) setting reply-to header to the address of the author of the change 3) setting it to a fixed address (like noreply@some.place) Proposal by Peter Funk (pefu) in discussion with Tom Ekberg (tekberg). I chose to re-retrieve the email address for the author from the database rather than adding a new variable. Also managed to make a test case for each of the three settings.
