title: WebDriverIO: waitFor <title> to be X
body: <p>Is there a pattern with the current <code>2.0</code> library that would allow me to wait until the current Page's title is X? For the purpose of pausing the WebDriver until I am on the page I wish to be after several redirects?</p>
  
  <p>This would be easy if I could do <code>driver.waitFor('title:contains("Google")');</code></p>
