feat: restore locale level translations for other packages (fixes #41)

This is only a partial fix though, it basically restores the old behavior as a default. That doesn't help though with flipping the definitions to get stuff out of the UI Locale file though. So that'll have to come next for allowing wildcard resolutions to be done from the game(?) or maybe locale extension files?
