Upgrade selenium version to 0.40
Update to Selenium 2.41, breaking binary compat

Careful: this version of Xebium will not work unless your project is also on
Selenium version 2.41, because the WebDriverCommandProcessor we're using from
Selenium has moved packages upstream.

If the selenium dependency is pulled into your project via Xebium, you should
be fine, but be careful otherwise.
