  Both `gamer_id` and `gamer_secret` are returned by `/v1/gamer/login`.
  
  It is your responsibility to store these to help the user log in later.
  
  Login for authenticated gamers will one of these : 
  
  * Facebook identity: use the `ID` and the `oauth token` from Facebook
  
  * Google+ identity: use the `ID` and the `oauth token` from Google+
  
  * RAW: use the `gamer_id` and the `gamer_secret` from a previous login
  
      Note: I've added RAW as a mean to login again, with gamer_id:secret
