title: Permission Dialog button label is "Go to app" instead of "Login with Facebook"
body: <p>I have a page with a "Login with Facebook" button. (We use Java+Spring Social).
  If user clicks on this button it submits the form for: /social/signin/facebook
  The Permission Dialog opens, but the Button's label on it is "Go to app". What should I do to make this label be "Login with Facebook" and not "Go to app"? I tried the display:popup parameter, but the label was the same with it.</p>
  
  <p>In another project we don't use Spring Source. We make the Fb login with this call:</p>
  
  <pre><code>FB.login(
    function(response) {
      if(response.authResponse) {
        window.location = ...
      } else {
        alert(accessDeniedMessage);                                                 
      }
  },{scope : REQUIRED_PERMISSIONS});
  </code></pre>
  
  <p>and this case the button in the Permission Dialog is "Login with Facebook".</p>
