Change the behaviour of --nautilus-view such that the process doesn't exit

2003-10-16  Mark McLoughlin  <mark@skynet.ie>

        Change the behaviour of --nautilus-view such that the process
        doesn't exit until the last control has been destroyed. The
        previous behaviour caused intermittent activation failure
        when the process timed out and died before the view could be
        created - bug #124768.

        * src/ephy-main.c:
        (ephy_main_start): don't unref the shell when started with
        --nautilus-view.
        (ephy_main_dummy_url_argument),
        (ephy_main_translate_url_arguments): create a dummy argument
        when no arguments are supplied which will cause the default
        window to be opened.

        * src/ephy-shell.c:
        (ephy_nautilus_view_all_controls_dead): unref the shell
        here causing the process to exit.
        (ephy_nautilus_view_init_factory): setup the all_controls_dead
        callback.
        (ephy_nautilus_view_new): instrument the control.
