Emit scrolling-related events

[xzilja]

I'm writing some logic that needs to be started on scroll start and ended when scrolling ends / becomes idle.

I can detect scroll start with scrolbar.addListener listener, but I can't seem to find anything that indicates "stop" event i.e. when scrollbars become idle and user is no longer pressing on the screen / using mouse wheel.

Is event like this exposed? If not what would be right approach here?

#126 this works, perhaps it could be a good idea to expose end event however?

Maybe we can write a plugin that emits all the related events (e.g. scroll-start, scroll-end, etc.). I'll consider adding this in the next major release, thanks!
