[evolution-data-server/openismus-work-master: 12/137] ECollator: Remove the "collation_type" option.

[Tristan Van Berkom <tvb src gnome org>]

commit a8803669bfa2da147a05ce68ef7c21823bdbbc1e
Author: Tristan Van Berkom <tristanvb openismus com>

    ECollator: Remove the "collation_type" option.
    
    Instead ECollator will try to make a best guess at what
    type of collation is desired for a given language
