[gtk+/wip/baedert/gtk-widget-destroy: 140/149] window: Add gtk_window_destroy

[Timm Bäder <baedert src gnome org>]

    window: Add gtk_window_destroy
    
    Instead of relying on the hacky g_object_run_dispose, simply do what
    gtk_window_destroy should be doing: Remove the window from the internal
    list of toplevels and unref it.
    
    To be used on windows instead of gtk_widget_destroy.
