Bug #914 - ClutterEntry is confused about characters vs. bytes

* clutter/clutter-entry.c: (clutter_entry_ensure_layout),
        (clutter_entry_handle_key_event_internal),
        (clutter_entry_set_text):
        Fix mix-up of character and byte counts, handle unicode correctly.
        Use clutter_key_event_unicode() instead of
        clutter_keysym_to_unicode().

        * clutter/clutter-event.c: (clutter_key_event_unicode):
        Don't ignore ClutterKeyEvent.unicode_value

        * clutter/clutter-keysyms-table.h:
        Rename header define so as not to conflict with clutter-keysyms.h

        Patch originally by Emmanuele Bassi, with input from Tommi Komulainen.
