Matthias Clasen f8a1be3a04 Add a gtk-im-module GTK setting 
2007-12-17  Matthias Clasen  <mclasen@redhat.com>

        * gtk/gtksettings.c: Add a gtk-im-module GTK setting
        * gdk/win32/gdkproperty-win32.c:
        * gdk/x11/gdksettings.c: ...and back it by a Gtk/IMModule X setting.

        * gtk/gtkimmodule.[hc]:
        * gtk/gtkimmulticontext.[hc]: When determining the default context,
        look at the gtk-im-module setting, and listen for changes to the
        setting.  (#502446, Akira Tagoh)
