Bug 9471 - Use DataTables on serials claims page

Replace the tablesorter plugin with the DataTables plugin on the
serials claims page.

This patch replaces some custom table fitlering code with code which
uses DataTables' built-in table fitlering. A minor correction to markup
has also been made to properly align inputs in the filter form.

To test, run the serials claims report for a vendor with data which will
populate results. Confirm that table sorting works correctly. Confirm
also that filtering by title and branch works.

Works as advertised. I have compared side by side the both pages, with
tablesorter, and with DataTables. The both work. No regression. With
DataTables, no more sorting on Begin clam column, which is great. A new sort
option may be usefull on the Library column (wasn't the with tablesorter
neither).
