Add player statistics

[DylanBulmer]

In the server's data base file, we need to add a player stats section where each player's section will look like:

players: [
    {
        name: "Joe",
        stats: {
            territories: ["terr 1", "terr 2", "..."],
            population: <number>,
            etc.
        }
    }
]

Then write a function in the game.js file that can read and make a table of the players' stats
