Allow to specify arbitrary notification recipients.

* src/wydawca.h (enum notification_target): New value notify_read,
meaning "read recipient addresses from the message headers".
* src/config.c (target_args): New values: "read" and "message".
(target_types): New value 'notify_read'.
* src/mail.c (mail_send_message): Handle NULL rcpt.
(do_notify): Handle notify_read.
