feat(i18n): add support for translatable text replacement (#478)

* Rebase translation work for easier rebasing

* Fixed gradle setup

* Further translations

* Add a few more strings

* Remove support for pluralisation to match Minecraft and alleviate issues with over-complexity

* Further translations

* Added a tonne more translations

* Added the remaining translation nodes

* When custom files are found, use the base files for default values.

* Only download translations if a key is provided

* Fixed typo in brush radius too large

* Allow translation files to be missing entries, and use the english version in place.

* Fixed issues brought up in review

* Reverse translation order (#533)

* Fix a lot of PR comments

* Add JD to the Operation warned field due to no private fields in J8

* Only warn when there are messages
