Bug 11734 - Use new DataTables include in batch modification templates

Bug 10649 introduced a new include file for adding DataTables-related
JavaScript assets. This patch adds use of this include file to the
batch modification and batch deletion pages.

Minor text changes: Corrected capitalization.

Apply the patch and test the following:

- On batch modification and batch deletion, submit multiple barcodes or
  item numbers. On the results page the title column has been configured
  to use the "anti-the" filter to exclude articles from sorting. Sorting
  on all columns should work correctly.

Edit: Put back checkboxes plugin which was accidentally removed.
