Make it work, even if the window is already realized or mapped.

        * gtk/gtkwindow.c (gtk_window_set_screen): Make it
        work, even if the window is already realized or
        mapped.

        * tests/testgtk.c: Erwann's multihead changes, slightly
        dumbed down. (Removed logic for pulling windows onto
        the current screen, people can click twice on the demo
        to destroy and create again.)

        * tests/prop-editor.c: Set the screen on the property
        editor if the edited object is a widget.
