[aur-dev][PATCH] notify: add X-AUR-Reason header to allow conveniently filtering emails

[Eli Schwartz]

Because filtering by matching the sender && regular expressions on the

In order to remain generic enough to allow the notify script to be
imported from and used elsewhere, we cannot just use sys.argv[1] as the
reason.
