title: What props can be passed to Navigator.push
body: <p>I've been searching for about an hour now with 0 results to this question. I'm just looking for a list of the props that can be used when calling <code>navigator.push</code>, specifically how I can use the <code>sceneConfig</code> prop in the call, but a whole list would be really helpful. Of course like always Facebooks documentation is only half baked and quite vague.</p>
  
  <p>What do I pass to <code>navigator.push</code>? I need all the keys and values for the object that could be passed into the function.</p>
