Subject: [PATCH] Get AUTHOR_DATE from the email Date: line

Now that git does pretty reliable date parsing, we might as well get
the date from the email itself. Of course, it's still questionable
whether the date on the email is all that relevant, but it's certainly
no worse than taking the commit date.
