Fix camera node for NAO version 3.2 with Naoqi 1.14. Changed the camProxy.subscribe() which was deprecated to the subscribeCamera, and as the call was the same for both versions removed the if for the version. Also changed the auto_Exposure_algo parameter to 0 as the parameters 2 and 3 were not valid for this NAO model (it gave an error), so parameter 0 and 1 should work for every NAO.
