Title: Correctly return to main page when switchToIFrame() is called

In facebooks new php-webdriver module, when you want to switch to the
main window instead of an iframe, there is a new function defaultContent().
This update modifies the WebDriver module to match the behavior of the existing
Selenium2 module and the provided documentation. This could alternatively be
accomplished by changing the default $name = array(), as that is what
defaultContent() passes, but using their methods struck me as a better choice.
