Bug 15581: Display the latest auto renew date possible when renewing manually

If an issue marked as auto_renew is renewed manually, we want to display
the latest auto renew date possible.

Test plan:
1/ Define circ rules as in the previous patch.
2/ Check a item out, mark it as an auto renewal
3/ Back date the issuedate and make sure it will be too late to renew it
4/ Use the Circulation > renew page (circ/renew.pl) to manually renew
this issue.
You should get a warning "You barcode has been scheduled for automatic renewal
and cannot be renewed anymore since DATE."
If the pref AllowRenewalLimitOverride is set, you will be allowed to
renew it anyway.
