I'm quite unsure about this. The idea of translations is good, however I feel like having customizeable messages per envoy is a good sellingpoint of the plugin, and this would just remove that feature completely. Another thing is that we would have to migrate the messages from their existing messages.yml.

I think a better solution would be to have a locale option in the config, have a default lang folder, slap the current messages.yml there with the default translation (en_US.yml) and leave it at that with the previous system for messages.

I really appreciate your work, however next time please ask me (Discord: tomtom4945) about how things should be implemented, so we don't run unnecessary laps. :D

Thank you for your comments on this pull request. I will be probably closing it soon as the translation system is kinda overwelming to implement on an already released plugin.
