[balsa/gtk3] Use Gspell-1.2 API

[Peter Bloomfield <peterb src gnome org>]

commit a23ef4c2d80073f39af57206fac50088466df212
Author: Peter Bloomfield <PeterBloomfield bellsouth net>
Date:   Thu Jun 30 15:57:01 2016 -0400

    Use Gspell-1.2 API
    
        * configure.ac: check whether we can use the Gspell-1.2 API;
        * src/sendmsg-window.c (create_text_area): if so, set the
          enable-language-menu property, to allow the user to change the
          spell-checker language from the context menu as well as from
          Balsa's menubar menu.
