    Net: Fix off-grid dragging, including a segfault
    
    When a drag started outside the grid (or no drag has started yet),
    ensure the drag state in game_ui says so and bail out accordingly.
    
    Previously, such a drag would manipulate the tile the last valid drag
    started from, if any, else segfault.
    
    Also, allow drags that start on-grid and then go off-grid to continue
    rotating.
