[gnome-font-viewer] font-model: use g_utf8_collation_key to sort the model

[Cosimo Cecchi <cosimoc src gnome org>]

commit d6a52781adb99e318b8b419ffd0b3521cc0893f5
Author: Cosimo Cecchi <cosimoc gnome org>
Date:   Mon Jun 11 16:36:33 2012 -0400

    font-model: use g_utf8_collation_key to sort the model
    
    So that we get the right sort order according to the current locale.
    Store the collation key in the model to avoid a performance hit.
