Bug 21428: Update two-column templates with Bootstrap grid: Reports part 1

Bug 21428: Update two-column templates with Bootstrap grid: Reports part 1

This patch modifies several administration 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:

 - Reports -> Acquisitions statistics wizard
 - Reports -> Patrons with the most checkouts
 - Reports -> Patrons who haven't checked out
 - Reports -> Patrons statistics wizard
 - Reports -> Cash register statistics wizard
 - Reports -> Most-circulated items
