Title: Navigation outline needs to be scrollable and have a max-height.

See the outline navigation (right side) on long articles like [How Browsers Work](http://www.html5rocks.com/en/tutorials/internals/howbrowserswork/) for why this is necessary.

This simple patch sets a max-height of 500px for the outline navigation and makes it scrollable.
