webdriver.js integration

[tbosch]

It would be nice to be able to write tests using webdriver.js and execute them using uitest.js. Some kind of the old Selenium RC, but with the new webdriver API.

Guideline

• intercept webdriver.js when it does the remote request
• use jquery for implementing the query part of the webdriver.js protocol
• use some other library for simulating browser events using Event.dispatchEvent...
