gnome-documents strings changes

[Cosimo Cecchi <cosimoc gnome org>]

Hi all,

Andre pointed out to me on IRC the recent string changes in gnome-documents might be considered a string freeze break.

The strings didn't actually change, but disambiguation contexts have been added as requested here [1] [2].

Since gnome-documents hasn't yet been branched for gnome-3-8, I could branch it from a commit previous to the introduction of these comments if they constitute a break, even if that kinda defeats the original purpose of the fix...

Let me know what you prefer!

Please CC me on the reply, thanks.

Cosimo
