[glom/glom-1-20] Choices: Make sure related choices are sorted.



commit 5ec840748d7f28e6df82604b296c9345e4d494e1
Author: Murray Cumming <murrayc murrayc com>
Date:   Sat Dec 24 16:40:21 2011 +0100

    Choices: Make sure related choices are sorted.
    
    * glom/mode_data/datawidget/combochoiceswithtreemodel.cc:
    set_choices_related(): Add a sort clause, though it would be best if
    the developer could specify this.
    Note that Utils::get_choice_values(), used for other choices, already
    does this, and we should reduce the code duplication.
