    appIcon: Use a real BaseIcon as the drag actor
    
    Moving an app icon to other positions is semantically different
    to dragging an actor to the dash; the act of moving should itself
    be semantic, in that we should feel like we are moving the actual
    icon.
    
    Currently, AppIcon gives the DnD code a simplified version of itself,
    with just its icon, instead of a complete copy with the label.
    
    Make AppIcon create a new IconGrid.BaseIcon and use it as the drag
    actor.
