Currently command localization is hardcoded. Would be cool if it will be translatable.

Note for future contributors: StatCollector.translateToLocal nor StringUtils(I guess?) shouldn't work serverside, it means that server always will display English text since server language is English.
Everything should be changed to ChatComponentTranslation, this should translate messages on serverside. I tried to do it myself but I have not enough experience in mod coding. My messages always stays as unlocalized name.
