Finished basic user accounts and game creation. Game currently supports one game per user. On the landing page, if a user is not logged in, they can do so and will automatically return to the landing page with a logged in state. Once logged in, If the user is currently in a game that has an opponent, client redirects to the game. If the user is not in a game, an open game is created if the user is not already in an open game. The user will then wait until an opponent joins the game. Currently, the user will not be automatically redirected to the game if an opponent joins the game while they are waiting on the landing page.
