Title: Safari 6 scroll issue with DD

This patches the issue with Safari 6 and scrolling.

It's a total patch, but it seems like this:

```
var node = Y.one(window);
node.set('scrollTop', 100);
node.set('scrollLeft', 100);
```

And this

```
window.scrollTo(100, 100);
```

Do different things in Safari 6 now, need to ping @msweeney about this.

This patch uses `window.scrollTo` under the hood when scrolling a window object
