- Load the language files correctly when language is changed
- Save user language in localstorage so that we can have it even if disconnected (but still load it from user settings eventually since
user might be on a different device)
- Load all locales from Cldr with Gettext
- Fix pt-PT -> pt-BR
- Clean some obsolete config.exs comments
Later changes will allow to set the language without an account
