Bug 21433: Update two-column templates with Bootstrap grid: Tools part 1

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 in the modified templates.

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

 - Tools -> Automatic item modifications by age
   - View and edit rules
 - Tools -> Batch item modification start page
 - Tools -> Batch delete records
   - Starting page
   - Confirmation page
   - Completion page
 - Tools -> Batch record modification
   - Starting page
   - Confirmation page
   - Completion page
 - Tools -> Batch patron deletion/anonymization
   - Starting page
   - Confirmation page
   - Completion page
 - Tools -> CSV profiles
   - View and edit CSV profiles
