Bug 21570: Update two-column templates with Bootstrap grid: Various

This patch modifies several assorted 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:

 - Administration -> Plugins
 - Tools -> Comments
 - Acquisitions -> Suggestions
 - Lists
