title: Where do you set app properties normally specified in the appmanifest file?
body: <p>I am trying to change</p>
  
  <ul>
  <li>the name of the splash screen file for Windows 8 app</li>
  <li>the background colour. It is set to dark grey currently.</li>
  </ul>
  
  <p>Can't find it anywhere in the config.xml</p>
  
  <p>Those are normally set in the .appxmanifest file</p>
