Freeze break request for GNOME Nibbles

[Michael Catanzaro <mcatanzaro gnome org>]

Hi,

I'd like to push the Nibbles patches in these i18n bugs:

https://bugzilla.gnome.org/show_bug.cgi?id=763905
https://bugzilla.gnome.org/show_bug.cgi?id=763906

The first patch adds a few colors ("red" "green" "blue" "yellow" "cyan"
"purple") as new translatable strings. Apologies for the very late
string additions; the strings are already displayed in the UI, but not
currently marked for translation.

Michael
