Bug 22981: Remove type attribute from script tags: Catalog

Bug 22981: Remove type attribute from script tags: Catalog

This patch removes the "type" attribute from <script> tags in several
catalog-related templates.

To test, apply the patch and confirm that the following work properly
without any JavaScript errors in the browser console:

 - Catalog -> Advanced search
 - Catalog -> Item search
 - Search history

Validating the HTML source of these pages should return no errors
related to the "type" attribute.
