Added/changed by Lars Gunther:
+ This script has been made XHTML-secure (createElementNS) See jsUtilities.js
+ If there are no links no header or ul will be added
+ Added heading-argument to provide basic i18n or other customization of the heading
+ Uses John Resig's addEvent instead of Scott Andrews'
+ MAJOR BIG FIX: MSIE harvests the src-attribute for images as well -> STOPPED
