title: Event handler for close/force stop an ionic app
body: <p>I am developing an ionic app. I am wondering if there is any event handler for this condition when the app is being stop/close in follow ways:<br>
  1) Settings -> Application -> Application Name -> Force stop <br>
  2) Swipe to close app. <br></p>
  
  <p>I would expect something like this. But the best i could found is to cater for app exiting via <code>$ionicPlatform.registerBackButtonAction</code> which does not include the above two scenario.</p>
  
  <p>Also, I am not sure whether this can be done in native platform as well. Please advise on this.</p>
  
  <pre><code>angular.module('app').run(function($ionicPlatform) {
      $ionicPlatform.onAppStopOrForceClose(function() {
          // Any function here
      });
  });
  </code></pre>
