[Webtest] [dev] support for js confirm()...

> What do you think (I can develop more if needed)?

Why do you need two threads? Isn't that going to make the architecture
more complex? Why not enable some sort of interceptor (additional
plugable layer) for the javascript functionality?

If the button or link has some javascript properties, the
'interceptor' will check the condition and affect the overall result.

On short, in our project we had this 'places' where the user could
insert certain conditions in the workflow - to deal with them we
created a stack of event, user configurable, that were executed before
the result was concluded by the same thread.

Just an idea..
