Always run at 60 FPS

I think it would be easier (and maybe better) to just always run the app at 60(ish) FPS, this is what works best with PIXI.

So just

var animate = function() {
    requestAnimFrame(animate);
    renderer.render(stage);
}
requestAnimFrame(animate);

This solves a lot of dependency problems, where every object that updates has to call the animate function in main. I think WebGL is smart enough to just don't go crazy when it isn't needed.

It is a lot less smooth :|
