title: android:screenOrientation tag in application does not work
body: <p>The <code>android:screenOrientation</code> tag when placed in <code>&lt;application&gt;</code> does not work.
  But when I put <code>android:screenOrientation</code> in a <code>&lt;activity&gt;</code> tag it works.</p>
  
  <p>If <code>android:screenOrientation</code> tag works in <code>&lt;application&gt;</code> then, there would no need to put <code>android:screenOrientation</code> handling for every activity.</p>
  
  <p>I wonder, why there is such strange behavior in Android platform for <code>screenOrientation</code> tag?</p>
