title: Cocos2D logging "[Action update]. override me" in every tick
body: <p>Is this a problem? I believe that the warning:
  <code>[Action update]. override me</code>
  comes from directly calling [myAction update] on my own action. Which I'm not doing.</p>
  
  <p>Can I just comment out the log warning? This gives me a dirty feeling. But everything seems to work fine...</p>
  
  <p>This was in Cocos2D 1.1 and also in 2.0rc2.</p>
