Batch Patron Modification has a fairly long run/load time. I have attempted to
improve the runtime of the Batch Patron Modification tool and my enhancement
reduces the time to modify a batch of patrons by an average of 44.02%

I discovered the extended runtime was mostly due to detailed data retrieval in
preparation for display. The overhead for a batch of 1000 patrons was enough
that I have changed functionality so that if there are more than 20 patrons in
the batch to simply display a success message instead of the details of every
changed patron. There are other small code logic improvements also included to
prevent unnecessary function calls.

In the end my test case of 1000 patrons originally took 59.02 seconds to
modify, after optimisation it took 33.04 seconds saving 25.98 seconds.
