Update: Scroll preferences window content on Drag-and-Drop

Browse source 
Scroll the content of the preferences window on Drag-and-Drop, when the
mouse is in the upper or lower part of the content of the preferences
window.
This helps a user, who has e.g. a lot of items, but the preferences
window with a low height, to easily move any item to any position.
