Initializes an app for use with Game Center.
If using/testing Game Center on iOS 8.x and Xcode 6+, you must enable the Game Center sandbox by opening the Settings app on the device, selecting Game Center and enabling Sandbox.
gameNetwork.init( "gamecenter" [, initCallback] )
Listener. Callback function where, upon successful login, event.data will be true. If unsuccessful, event.data will be false. When problems such as network errors occur, event.errorCode (integer) and event.errorMessage (string) will be defined.
The event.type called "showSignIn" will be invoked before the Game Center login screen appears. This gives you a chance to pause your game or do any special actions you need before the login view takes over the screen. On successful login, event.data will return the login status (presumably false), so code which does not check for this type will still work. When this view is dismissed, the callback will be invoked again with event.type set to "init" to handle the results of the login.
Be aware that iOS backgrounding will cause your app to automatically log out the user from Game Center. When the app is resumed, Game Center will automatically try to
