[evolution-data-server/openismus-work-master: 40/41] ECollator: Use the private EAlphabetIndex

[Tristan Van Berkom <tvb src gnome org>]

commit 437c43bd907414d754274e0f43cc421aa60ef1b4
Author: Tristan Van Berkom <tristanvb openismus com>
Date:   Fri Jun 7 22:44:08 2013 +0900

    ECollator: Use the private EAlphabetIndex
    
    This allows ECollator to export 2 new APIs:
    
      o e_collator_get_index_labels()
    
        List the alphabet for the given locale
    
      o e_collator_get_index()
    
        Determine what position in the alphabet a given word belongs
