New email-related meta-variables.

These variables make it possible to avoid setting
`recipient' statement in `notify' blocks, instead
specifying recipients directly in the message
headers and using the default recipient setting, which
is `read'.

* src/mail.c (expand_email_admin)
(expand_email_owner): New functions.
* src/triplet.c (triplet_processor): Remove the
triplet if process_directives returns !0.
(expand_email_user): New function.
(triplet_meta): New keywords email:user (not to
be confused with user:email), email:admin and
email:owner.
* src/wydawca.h (expand_email_admin)
(expand_email_owner): New functions.

* NEWS, doc/wydawca.texi: Updated.
