Add leaderboards / showing of popular games

[larsenv]

We would like to make a page that shows the people with the most coins (the number of games played == the number of coins).

We also would like to make a page showing the most popular games.

For the former, I'm worried that a leaderboard would encourage people to find a way to cheat (you can only get 1 coin per minute, so it would be harder to rack up coins).

For the latter, we might have to make a new JSON file to keep track of the games rather than reading the games from everyone's JSON.

@TheShadowEevee FYI, @bennyman123abc says he has done some work on leaderboards, but it's been a while since he touched it...

If you want him to finish it, please ask him politely on Discord.

@larsenv I think you misunderstood; I said I didn't want to work on the leaderboards. I haven't done anything related to them, lol

[larsenv]

I said FYI for a reason...

Oh shoot; I was focused on my PR and only halfway thought that through, I read the names backwards. I see what you mean now, sorry.
