Subject: [PATCH] Bug 11577: Add an automatic renewal cronjob
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch adds a new cron script automatic_renewals.pl and a new
entry in crontab.example.

To test:

1) You need a few issues, some with automatic renewal and some without.
2) Confirm that each time you run misc/cronjobs/automatic_renewals.pl
   those issues are renewed that meet all of the following criteria:
   - automatic renewal has been scheduled either by issuing rule or by
     checkbox on the checkout page
   - the number of allowed renewals isn't exceeded
   - renewal isn't premature (No renewal before)
3) Confirm that all other issues are not affected.
