Bug #916 - ClutterKeyEvent:unicode_value is ignored

Bug #950 - AltGr not handled 

        * clutter/osx/clutter-event-osx.c: (clutter_event_osx_translate):
        * clutter/x11/clutter-event-x11.c: (translate_key_event):
        * tests/test-events.c: (fill_keybuf), (input_cb):
        Apply patch from Tommi Komulainen, fill the unicode_value attribute of
        the ClutterKeyEvent struct. Also use XKeycodeToKeysym, as suggested in
        bug #950, comment #2
