Fix a hang on launch caused apparently by calling GAC sharedController twice in the same stack.  dispatch_once apparently doesn't like this, as it hangs.  Move all sharedInstance refs down to GAC applicationDidFinishLaunching so that any possible reference to GAC sharedController is done after GAC has finished its init.
