Bug 21792: Switch two-column templates to Bootstrap grid: Serials part 3

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 go to Serials.

 - Add or edit a new subscription. The "create an item..." and "do not
   create an item..." labels should look correct.
 - Search for subscriptions
   - Select two or more subscriptions to batch edit.
     - The subscription batch edit page should look correct and adjust
       well to various browser widths.
   - View a subscription and click the "Renew" button. The subscription
     renewal pop-up window should look correct.
