Handle locale stuff downloading of main thread and add doc to Object2IntBiMap
Technically LocaleUtils is not thread safe and people running Geyser for the first time on slow internet connections may see some untranslated messages. However, we were seeing startup times of about 1+ minutes on these slow connections, and it's better that players see untranslated messages for a short period of time rather than having to wait over a minute for the program to start up. Once the locale is installed, it doesn't need to be redownloaded again (unless there is a game update) and all translated messages will just work once this download is complete without clients needing to relog.
