1.21.5 support: updated PlayerStat's libraries to ensure the share-button and hover text are working again on the latest version
Some general code cleanup: a long time ago, I was working on a database support feature, but halfway through I lost my passion for it and got stuck. Ever since then I've had two versions of my code - the PlayerStats as it's published, and my own draft versions with half finished things all over the place. It's difficult to figure out what all my plans and intentions were exactly, but I did finally manage to extract all the non-database related improvements I had made. I've put the database-stuff to the side for now. Maybe one day I'll continue with it, but for now it's at least easier to update PlayerStats to keep it working on new Minecraft versions.
