Gamer's Glee

-fixed a major issue where Defusal tile state was not properly checked before revealing tiles. This caused multiple bugs such as the reveal sound being played when clicking a previously-revealed tile and players having the ability to "override" bombs by revealing a flagged/question-marked tile, putting the game in a softlocked state where the player can never flag that bomb again

-the Discord invite link is now fetched from the internet, allowing me to remotely update the link shown in-game should the invite link change

-the update.json file used by the update checker is now stored in a different repository from the main project
