Adds a UI icon in the top-right corner that displays the status of the Gameplay Systems. It flashes amber while GS initializes, turns red if any initialization fails, and turns green when everything has finished loading. If something causes the mod to break mid-game (highly unlikely), the UI comes back and warns the player.
When the game is freezing, the UI may not update its amber flashes. There is no need to close the game because the background initialization is still happening.
