[Webtest] For info: upgraded htmlunit

[Marc Guillemot]

Hi,

I've upgraded the htmlunit jar and related libs to current build from htmlunit's cvs. This makes the last changes in 
htmlunit available for webtest too:
http://htmlunit.sourceforge.net/changes-report.html

The main changes are:
- improved JavaScript support: events, outerHTML, insertAdjacentHTML, innerHTML, ...
- upgrate from commons-httpclient-2.0.1.jar to commons-httpclient-3.0-beta1.jar
- upgrate of Rhino javascript engine from js-1.5R4.1.jar to js-1.6R1.jar
- upgrate of the html parser nekohtml-0.8.1.jar to nekohtml-0.9.4.jar

If the server wakes up to perform a build, this should be available in build 644.

Marc.
