Bug 16548 - All libraries selected on Tools -> Export Data screen

This patch adds "select all" and "select none" links to the display of
libraries in the export bibliographic records form.

Also modified: call number range and accession date fields have been
grouped in their own fieldsets in the hopes that this is more readable.
Page title and breadcrumbs have been corrected to read "Export data"
instead of "MARC export," matching menu items.

To test, apply the patch and go to Tools -> Export data.

- Test the select all/select none links and confirm that they work as
  expected.
- Confirm that the structural changes to the form look okay.
