title: reasking for declined permissions in fb js sdk
body: <p>I'm using <code>FB.getLoginStatus()</code> to check for login which will display authorization dialog in case it's needed.<br/>
  the case here, if that the user unchecked email from the below screen, the screen will not attempt to re-ask the user by displaying the dialog, and calling FB.login will result in a warning that user is already authenticated. there is a way i can pass a scope with recheck option to <code>FB.getLoginStatus()</code>? or any other solutions to set me on the right track</p>
  
  <pre><code>function checkLoginState() {
      FB.getLoginStatus(function (response) {
          //console.log('statusChangeCallback');
          //console.log(response);
          if (response.status === 'connected') {
              // Logged into your app and Facebook.
              LogUserIn();
          } else if (response.status === 'not_authorized') {
              //console.log('you must authorize the app');
              alert(message);
          } else {
              //console.log('Please log into Facebook.');
          }
      });
  }
  </code></pre>
