Public methods for Inertia Scrolling #477

So far the hc:ScrollViewer has supported inertia scrolling for mouse wheel, but has no public method of doing so programmatically. For example, I needed to add button to scroll fixed offset every time, which makes me found this problem.

Describe the solution you'd like

I know there are some internal methods in ScrollViewer for inertia scrolling, so we can just simply use them to override the system native methods.
