Bug 21434: Update two-column templates with Bootstrap grid: Tools part 2

This patch modifies several tools templates to use the
Bootstrap grid instead of YUI.

This patch also removes obsolete "text/javascript" attributes from
<script> tags and "text/css" attributes from <style> tags in the
modified templates.

To test, apply the patch and view the following pages, confirming that
they look correct at various browser widths:

 - Tools -> Export data
 - Tools -> Calendar
 - Tools -> Import patrons
 - Tools -> Inventory
 - Tools -> Staged MARC management
   - View batches and batch details
