Scrollbar for easier scrolling

[xstable]

I would love to have an scrollbar to easily scroll longer distances in the view. Currently it's only possible to use the scroll of the mouse.

Yeah, I am using GNOME and in GNOME there is a scrollbar, so I didn't know that is missing O:-)
Scrollbar will be added in next version.

Edit:
Added in v 1.0.10
