Bug 7444: Update circ/circulation.pl to use KohaDates TT Plugin

Bug 7444: Update circ/circulation.pl to use KohaDates TT Plugin

Removes all date formatting done in circ/circulation, and sets any/all date
outputs to iso format.  The formatting of dates is now handled in the template
using the KohaDates plugin.

This allows use to remove a dependency on C4/Dates.pm from the script.

This patch also removes the usage of C4/Overdues/CheckBorrowerDebarred.  Since
borrowers.debarred is returned by GetMemberDetails, it doesn't make sense to
include another module to run another MySQL query just to fetch the date again.

To Test:

1. View the checkout page for a patron with materials checked out today and in days past, as
well as items on reserve.
2. View a patron who is nearing their expiry date
3. Renew a patron
4. Renew a material from the checkout page using the renewal date selector
5. Attempt to checkout a book to a patron that is on hold for someone else
6. Attempt to checkout a book that is currently checked out
7. View a debarred patron

In all cases, any dates displayed should be in syspref format
