    app: do not run gtk_window_present() in about_dialog_create().
    
    The window will be raised soon after anyway. No need to do it too early,
    which makes setting a transient parent useless afterwards. In particular
    we were still getting a "GtkDialog mapped without a transient parent"
    message.
