[Webtest] Javascript support ready!

[Dierk Koenig]

Hiall,

I'm happy to announce the first Version of CanooWebTest that also
supports JavaScript. This concerns build number 275 and higher.

I'm sure the community will find a lot of deficiencies in the JS
implementation but I hope you will appreciate it anyway.

I unexpectedly re-introduced the "testCacheBug", although I tried
to avoid it. Carsten: could you please help me with that?

I would recommend to try this build on a separate installation as
some changes may break a lot of your tests. The parser is now
somewhat sloppy (like most browsers).

happy testing
Mittie

P.S. new httpunit version in use is 1.5.3-d-12M
