Add DropArea item and Drag attached property.
Refactors drag API to improve compatibility with traditional drag and drop by reusing events and adding drop actions. Event sending is removed from MouseArea, instead the Drag object can be attached to the item that is dragged and it will send drag events when the position of that item is changed or when its active property changes. The DragTarget item is renamed to DropArea and can now communicate supported and suggested actions.
