Bug 23626 - Add a system preference to limit the number of rows of data used in
a chart when viewing report results

The number of rows generated by a report is potentially unlimited; this has the
potential to exhaust all available memory, bringing a Koha server down to its
knees.

The attached patch introduces a system preference to limit the number of rows
used when charting report results; at this time, and with bug #23624 fixed,
that is the only aspect of reporting that loads all results into memory at
once.
