Bug 12018 - add table sorting to patron card batches

When viewing batches of patrons in the patron card creator module the
table is not sortable. This patch adds table sorting.

The patch also makes some corrections of invalid markup and moves
informational/error messages to the top of the page rather than in a
sidebar. This change lets the table and sorting controls expand into a
wider space.

This patch also corrects a translation issue with table headers
identical to that addressed by Bug 11505.

To test, go to Tools -> Patron card creator -> Manage batches.
View an existing batch or create a new batch and populate it with
patrons. Table sorting controls should work correctly. Batch management
operations should work correctly.
