Mainmenu game-related changes (#11887)
fixes: * Switching between games does not immediately hide creative mode / damage buttons if so specified * World creation menu has a game selection list even though the menu already provides a gamebar * Showing gameid in world list is unnecessary * Choice of mapgen parameters in menu persists between games (and was half-broken)
