Subject: TPAC i18n: Turn UA locales into Evergreen locales
X-Git-Url: http://git.equinoxoli.org/?p=transitory.git;a=commitdiff_plain;h=44f601f85bd37095fa986ac43e13d851c243ba42

TPAC i18n: Turn UA locales into Evergreen locales

We need to convert the likes of fr_ca into fr-CA to be able to pull the
appropriate localized values from the database via CStoreEditor.
