title: TTNavigator three20 openURLAction
body: <p>I'm new to three20 and trying to find my way through the TTNavigator class.
  I try to push to a new view via the URL system.
  So I used openURL: animated: method which works just fine, but it's deprecated, and I know that I should use openURLAction instead, but this has no animated: parameter. Am I missing something?</p>
