[eog] Ask before showing Appearance capplet after setting wallpaper

[Felix Riemann <friemann src gnome org>]

commit f71a40269ae3b3ec3400e4d5352c064a6a7ffed5

    Ask before showing Appearance capplet after setting wallpaper
    
    This displays an info bar asking if the user actually wants to edit the
    style of his wallpaper. The info bar is hidden either by answering it or
    by selecting the next image. Confirming the question still opens the
    Appearance capplet as before. Fixes bug #606935.
