removed level.fillBG

added new graphics to several maps

to level developers: level.fillBG and level.fill no longer work,
you should draw backgrounds directly in level.custom like this:
level.custom = () => {
    ctx.fillStyle = "rgba(0,255,255,0.1)";
    ctx.fillRect(6400, -550, 300, 350);
    level.playerExitCheck();
    level.exit.draw();
    level.enter.draw();
};
