[Webtest] Canoo v1.6 build 544 (httpunit 1.6) Javascript Support?

[Marc Guillemot]

Concerning Date(), you're right: rhino complies to ECMA standard like Mozilla/Firefox but not IE. But the DOM objects 
are the job of htmlunit not of rhino. There are probably more IE specific objects/methods that are configured to work 
with rhino therefore I would rather say that the javascript support of htmlunit is closer to IE than to Mozilla/Firefox.
