Script tag to the bottom

As recomended by [Yahoo](http://developer.yahoo.com/blogs/ydn/high-performance-sites-rule-6-move-scripts-bottom-7200.html), <script src="..."/> causes 2 problems:
* Progressive rendering is blocked for all content below the script tag.
* Blocks download when it should be downloading an image or a font.
Move down the forgotten script on head
