title: Avoid status bar overlap on all screens
body: <p>I want all screens on my app to appear below the status bar on both iOS and Android, so I'd either have to add a <code>StatusBar</code> component or a <code>paddingTop</code> to all my screens.</p>
  
  <p>Is there a way to do this globally? Where is the appropriate top level component to add the <code>StatusBar</code> in a Redux app? (e.g. which part of <a href="https://github.com/react-community/react-navigation/tree/master/examples/ReduxExample" rel="noreferrer">https://github.com/react-community/react-navigation/tree/master/examples/ReduxExample</a>)?</p>
