Title: added scrollbar drag styling support

Added dragginCls param:
when user dragging scrollbar - this class adds to scrollbar, for best user experience and more native visualization while navigating in this manner.
(cause of without this solution when dragging scrollbar and move mouse out - it's no possible to show, that user interacts scrollbar, css :hover state and other pseudo classes not work)
