Bug 16344: Add a circ rule to limit the auto renewals given a specific

This patch adds a new circulation rule (no_auto_renewal_after_hard_limit) to block/allow
auto renewals after a given date.
The idea is to stop renewals at a given date. That way the library will have
time to send overdues and get the books back before the students do on holiday.

Test plan:
0/ Execute the update DB entry
1/ Define a rule with no_auto_renewal_after_hard_limit set to tomorrow
2/ Modify the issues.issuedate, to simulate a checkout in the past:
    UPDATE issues
    SET issuedate = "yyyy-mm-dd hh:mm:ss"
    WHERE itemnumber = YOUR_ITEMNUMBER;
with issuedate = 2 days before for instance
3/ Execute the automatic renewals cronjob script (misc/cronjobs/automatic_renewals.pl)
Confirm that the issue has been renewed
4/ Modify the no_auto_renewal_after_hard_limit and set it to yesterday
5/ Execute the automatic renewals cronjob script (misc/cronjobs/automatic_renewals.pl)
Confirm that the issue has not been renewed
