[gedit/wip/gtkapp-actions: 5/10] Handle basic command line options in main()

[SÃbastien Wilmet <swilmet src gnome org>]

commit f2d200f0dec587002c0537c467ff35443848b600

    Handle basic command line options in main()
    
    The i18n must be setup in the main() too.
    setlocale (LC_ALL, ""); is not needed, GTK+ does that for us.
