Bug 8971 - Sort holds queue report using DataTables

Replacing the old tablesorter plugin with DataTables on
this page will fix sorting bugs related to whitespace and
markup in table cells which tablesorter couldn't handle.

I have also taken the liberty of changing the default sort
from patron to call number, assuming that the librarian
uses this list to pull items from the shelf, and the shelf
is organized by call number.
