Fixed api call to correctly use ? instead of & as first query paramter

There's a mistake in the URL of the FB.api call to get friends:




FB.api('/me/friends&fields=name,picture', function(response) {




where & should be ? to delineate the first query parameter. 




This causes the call to fail, should be fixed in docs, and in the demo of the example:
