title: Phonegap 2.6 android inappbrowser opens on self despite _blank being passed
body: <p>I am using PhoneGap 2.6.0 with Sencha Touch 2.2 on Android 4.0.3. I am calling the InAppBrowser to open a share url to facebook like so:</p>
  
  <pre><code>window.open(encodeURI('https://www.facebook.com/sharer/sharer.php?u=http://www.mycoolapp.com/&amp;t=Everyone check this out'), '_blank', 'location=no');
  </code></pre>
  
  <p>However, instead of opening the InAppBrowser with the UI, it opens on top of my app screen without any 'OK' button like on iOS or any way to close and go back.</p>
  
  <p>I am able to go back with the standard Android OS back button.</p>
  
  <p>Is there any way to get the url bar and the OK button to show on the Android InAppBrowser for PhoneGap?</p>
