Create testing framework for all the selenium action

[cccs-shellyw]

Other than manually running Kangooroo are different websites, we have no good way of checking if the selenium actions are working properly. We don't know if it is clicking the correct element or pressing submit on the correct html element.

It would be nice if we can create a testing HTML page for creating more unit tests for Kangoooroo. Especially for the audiocaptcha solver.
