Bug 21523: Update two-column templates with Bootstrap grid: Serials part 2

This patch modifies several serials 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:

 - Serials home page
   - Subscription search
     - Subscription details
       - Edit history (under the "Planning" tab. Manual history must be
         enabled for that subscription).
       - Subscribers
 - Serials -> Manage frequencies
 - Serials -> Manage numbering patterns
