[eog] Emit the window's "prepared" signal from the main loop's thread

[Felix Riemann <friemann src gnome org>]

commit 5515f5c05186dc221abcbd4d028faefe52b71b5d
Author: Felix Riemann <friemann gnome org>
Date:   Wed Jul 1 22:10:48 2009 +0200

    Emit the window's "prepared" signal from the main loop's thread
    
    This simplifies the signal handler and should fix crashes with plugins
    using Clutter (at least Clutter-0.8) and possibly more.
