RFR: 8222526: Use of no longer existing jquery directory in script.js

[Hannes Wallnöfer]

Please review:

Issue: https://bugs.openjdk.java.net/browse/JDK-8222526
Webrev: http://cr.openjdk.java.net/~hannesw/8222526/webrev.00/

The dynamically created script element is redundant (there is a static element in the HTML file with the correct URL), so it only results in a warning in most browsers, but there may be environments where it is required for proper function.

Thanks,
Hannes
