Bug 9882 - Use DataTables on batch modifications pages

The batch modification pages (edit and delete) use the old tablesorter
plugin. They should use DataTables instead. This patch makes the
following changes:

- Remove tablesorter plugin from batchMod.tt where it was unused.
- Replace tablesorter assets with DataTables assets on batch edit and
  batch delete pages.
- Replace tablesorter code with DataTables code in batchMod.js, which
  provides table sorting functionality for both batch templates.
- Move position of batchMod.js script inclusion so that DataTables
  assets are loaded first.
- Remove inline table sorting code from batch edit page since it is
  provided by batchMod.js

To test, load barcodes on both the batch edit and batch delete pages.
Test JavaScript-based functionality on each results page:

- Check/Uncheck all
- Hide/show columns
- Table sorting on a variety of different kinds of data columns

Batch operations should complete normally.
There should be no JavaScript error on the batch operation "landing
page" (batchMod.tt).
