Update Unicode-Collate to CPAN version 0.66

  [DELTA]

  0.66  Sun Nov  7 10:47:30 2010
    - U::C::Locale newly supports locale: ko.
    - added Unicode::Collate::CJK::Korean for ko.
    - added t/loc_ko.t.
    - 12 compat. ideographs (e.g. U+FA0E) are treated as unified ideographs.
     (though DUCET also does it, now Unicode::Collate does it without DUCET.)
    - added t/compatui.t.
    ! Ideographs Ext.B (U+20000..U+2A6D6) can be overrided with UCA_Version 8.
      This is a long-standing behavior from Unicode::Collate 0.11 to 0.63.
      A wrong fix at 0.64 should be abandoned.
