scrolling direction should depend on your mouse scrolling setting, not the website settings

I was going to fork it on github and fix it but then I found this: http://www.nikolaydyankov.com/lionbars/

Seems to do the same job whilst respecting lion scroll direction (Haven't tested with standard scrolling so there's a chance they could have just imitated reverse scrolling)

It reverse scrolls with my mouse wheel, but I'm on Ubuntu. I wonder if Lion users are seeing reversed-reverse scroll.
