Bug 21442: Update two-column templates with Bootstrap grid: Circulation part 1

This patch modifies several circulation 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:

 - Circulation -> Pending on-site checkouts (enable OnSiteCheckouts
   preference).
    - Test with the CircSidebar system preference both on and off
 - Circulation -> Overdues
 - Circulation -> Holds to pull
 - Circulation -> Renew
    - Test with the CircSidebar system preference both on and off
 - Circulation -> Bibliographic detail page -> Request article (enable
   ArticleRequests system preferences)
 - Circulation -> Hold ratios
