[gnome-applets/wip/segeiger/window-picker-in-process: 8/8] windowpicker/applet.c: Replace grid with box

[Sebastian Geiger <segeiger src gnome org>]

    windowpicker/applet.c: Replace grid with box
    
    This fixes a problem on vertically aligned panels, that
    caused the task list to remain horizontal.
    
    This registers a callback to handle orientation changes of the panel.
