Bug 21430: Update two-column templates with Bootstrap grid: Reports part 3

Bug 21430: Update two-column templates with Bootstrap grid: Reports part 3

This patch modifies several reports 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 -> Items with no checkouts
 - Reports -> Catalog statistics wizard
 - Reports -> Guided reports dictionary
 - Reports -> Guided reports, saved SQL reports
 - Reports -> Average loan time
 - Reports -> Circulation statistics wizard
