[eog] Make EogPluginEngine GSEAL-compatible

[Felix Riemann <friemann src gnome org>]

commit 15d23daf9b43d9cb632033518ec88458b26d61e8
Author: Felix Riemann <friemann gnome org>

    Make EogPluginEngine GSEAL-compatible
    
    Has a workaround for the different behaviour of gtk_window_get_group()
    that makes sure that the configure dialog and its parent share a window
    group of their own as before. Not sure if it's needed.
    Part of bug 606883.
