title: matchmakerViewController:didFindMatch: does not get called to invited player?
body: <p>I am working on a multiplayer game using Game Kit.  "auto match" is working great, but not "invite friend."  The problem is that matchmakerViewController:didFindMatch: is not getting called on the invited player's device.  Is there some other delegate method that I'm not seeing, which I should be using for the invitee?</p>
  
  <p>I noticed in the apple docs, talking about this method, it says this:</p>
  
  <blockquote>
    <p>This method is called when the view controller’s hosted property is
    NO.</p>
  </blockquote>
  
  <p>Is this hosted property referring to the hosting device, or that the game is hosted on a server?</p>
