title: GPGAppstateModel does not exist in new gpg.framework 4.1.1
body: <p>After update to gpg.framework ver 4.1.1, I found out that GPGAppstateModel no longer exist, so some commands in my iOS game return an error.
  Example of the code I used to load token in my game:</p>
  
  <pre><code>GPGAppStateModel *model = [GPGManager sharedInstance].applicationModel.appState;
      NSNumber *totalTokensKey = [NSNumber numberWithInt:CloudSaveKey_TotalTokens];
  
      [model loadForKey:totalTokensKey completionHandler:^(GPGAppStateLoadStatus status, NSError *error) {
          if (status == GPGAppStateLoadStatusNotFound) {
              // Data for this key does not exist. This must be the first time our user
              // played this game
              NSLog(@"Total tokens does not exist");
  
          } else {}
  }
  </code></pre>
  
  <p>Is there anyway I can fix this?</p>
