Reciepe: Scroll view autoscroll

[ChrisChinchilla]

I think the recipes could be improved by adding more bite-sized example of common patterns. For instance: at this point, I struggle to figure out how to "auto-scroll" a scroll view when new messages are pushed in my chat app

You can set value to viewport-y property to scroll, however, I don't know the value range of it.
