/**
 * This class localizes various interface messages
 *
 * We use this class rather than editing the MediaWiki namespace
 * because editing the MediaWiki namespace only changes one language at a time,
 * whereas here it changes all languages at once
 * and also sends the messages for translation to translatewiki.net
 *
 * @note When calling wfMessage, we specify the language code to prevent errors like T302754
