Christopher Tate 3d4bf17f49 Add view/drawable states for drag-accepting / drag-hovered
Added new drag_can_accept and drag_hovered XML attributes and the View
logic to support them.  Drawable states are now refreshed automatically
when a drag starts/ends and when a drag crosses the boundary of a
participating view.
