RLG-Web: separate logging in and starting a game. The user now logs in with a username and password, receiving a token which is then used for any actions requiring authentication. Starting a game is one such action. Games use a different set of id keys. This allows users to supply their passwords once and then play any number of successive games. Also, newly registered users do not need to supply their passwords again.
