Bug 12587 - Improve output of filter information on patrons with the most checkouts report

This patch makes some changes to the way filter information is displayed
after running the patrons with the most checkouts report. Before this
patch several untranslatable English strings would be displayed, and
library and item type codes would be shown instead of descriptions.

To test, go to Reports -> Patrons checking out the most. Enter values
for all the filter options:

- Checkout date from
- Checkout date to
- Checkin date from
- Checkin date to
- Library
- Item type
- Patron category

When you submit the form and view the results you should see your date
submissions formatted according to your selected dateformat system
preference. The library name and item type names should be shown instead
of codes.

Improves translatability of the filters output after running
the report and the readability of them (removing codes).

Note: it would be nice if the read-only would be removed from the date
fields, as forcing people to use the date widget is a known accessibility
issue.
