Author: Kjell Ahlstedt <kjell ahlstedt bredband net>

    Application: Don't call add_window() before the application is registered.
    
    * gtk/src/application.[hg|ccg]: Move the call to add_window() from
    run(Window& window, int argc, char** argv) and run(Window& window) to
    on_activate_show_main_window() and rename it to
    on_activate_add_and_show_main_window(). Bug #681323.
