[Matthias Clasen <matthiasc src gnome org>]

commit 13e5e837985b9154873c82408ef77a8e20dfa30e
Author: Matthias Clasen <mclasen redhat com>
Date:   Tue Feb 16 18:33:16 2016 -0500

    Add message contexts to translated strings
    
    The string "None" is used in multiple contexts; add message contexts
    to give translators a chance to translate them accordingly.
