[gnome-control-center/wip/region-panel: 33/42] region: Make region filtering smarter

[Rui Matos <rtcm src gnome org>]

commit 9d7070aceee4709720d16ee6247dd1038e1c85b0

    region: Make region filtering smarter
    
    We normalize both the filter string from the user and the region label
    to disregard case and accents. Then we try to match the region label
    on its native translation, the current LC_MESSAGES translation and
    untranslated.
