Each game should be given an unique ID

Game is stored on the file system (path_to_games/id.json) and cached in memory

Past game can be loaded from the file system.

When a human vs human game is created, a master password is created for myself and a temporary password is created for the invitee.

When the invitee accepts the invitation, a new password is assigned and stored in the invitee's browser storage.

When either player plays a move or passes or resigns, the password must be sent along.
