#16 X-Virus-Scanned header

[Michael Grant]

I'd like to see the X-Virus-Scanned header which is
added to each email include which virus scanners
scanned the email instead of just "scanned by amavisd".

In particular, if it could also contain which version of the
software/datafiles, this would also be useful.

This is reminicent of spamassassin's x-spam header
where it tells you which tests succeeded.
