Leaderboards are up!

I finally had some time to wire a very basic leaderboard viewer webapp together, you can check it out here. It includes separate daily, weekly and all-time leaderboards for each game mode. I hastily coded a Cloudflare Worker which queries the Server/GetLeaderboard PlayFab API endpoint with a title secret and takes a leaderboard name as parameter; the leaderboard webapp queries this "API" asynchronously, so it should be up to date always.
