Bug 9635 - Replace YUI buttons on label batches pages with Bootstrap

This patch converts the toolbar used by label batches pages to
Bootstrap, replacing YUI button and menu code with Bootstrap markup.

This patch also consolidates the include file and main template. The
include file was used in only one template.

To test, create a label batch and test all functions related to that
batch: adding and removing items, de-duplicating the batch, exporting
individual items, exporting the batch, and deleting the batch. Buttons
should look correct and work correctly.
