Subject: [PATCH] Add an i18n infrastructure that allows for multiple different domains to receive translations from.  This allows for plugins to bind an i18n domain name to their translations, allowing for plugins to be shipped with their own gettext po/mo files and be displayed with the most appropriate translation.
