Bug 15582: Ability to block auto renewals if OPACFineNoRenewals is reached

If a patron owes more than the OPACFineNoRenewals value, the issue won't
be auto renewed anymore (driven by the new pref OPACFineNoRenewalsBlockAutoRenew).

Test plan:
Note: You will have to manually change data in your DB, make sure you
have access to the sql cli.
1/ Set the OPACFineNoRenewals to 5 (for instance)
2/ Set OPACFineNoRenewalsBlockAutoRenew to block
3/ Check an item out to a patron and mark is as an auto renewal
4/ Make sure the patron does not have any fees or charges.
5/ Execute the automatic renewals cronjob script (misc/cronjobs/automatic_renewals.pl)
Confirm that the issue has been renewed
6/ Create an invoice for this patron with a amount > OPACFineNoRenewals (6
for instance)
7/ Execute the automatic renewals cronjob script (misc/cronjobs/automatic_renewals.pl)
Confirm that the issue has not been renewed.
8/ Set OPACFineNoRenewalsBlockAutoRenew to allow
9/ Execute the automatic renewals cronjob script (misc/cronjobs/automatic_renewals.pl)
Confirm that the issue has been renewed
