Add new translations / Update old translations!

# 📝 New Translations
I want to introduce new translations and update current ones. Interested in "Hacktoberfest"? Here you can get started!

Any language is appreciated!
## ❓ How to contribute

- Create a fork
- Edit or add the corresponding file in [`/resources/lang`](https://github.com/thebigsmileXD/MagicWE2/tree/feature-flip-rotate/resources/lang), based on [the english translation found here](https://github.com/thebigsmileXD/MagicWE2/blob/PM4/resources/lang/eng.ini)
- If you modify an already existing language file, please make sure to remove entries that do not exist on `eng.ini`, and add those that are missing
- Create a pull request and reference this issue (referencing is optional)
- Pull Requests will be merged shortly before 30th October to leave you some time to correct translations (This does not influence Hacktoberfest, they are still counted if not merged)

Thanks to everyone who contributes!
## 🗒 Notes & Guidelines
- This is a Minecraft-related world editor, so some terms are special, i.e. "flood" has a similar meaning to the "Paint.exe paint bucket", and "Wand" is a region selection tool (See #64, there are several examples and explainations) (Please also check comments in this issue for some other special entries, like: https://github.com/thebigsmileXD/MagicWE2/issues/130#issuecomment-540112091)
- The translation files _**must be**_ named after the `iso639-2` 3-letter format (See https://www.loc.gov/standards/iso639-2/php/English_list.php)
- The language.name key _**must be**_ the "English Name of Language" entry from that website
- Translation strings must be enclosed by `" "`
- Readme may not be translated (too difficult to keep it updated)
## ❗ We had some discussions about some translation entries, so here is a heads-up on some things we have noticed:
- Please make sure that `{%0}` is properly kept and do not contain spaces, those are text placeholders!
- Make sure `//togglewand` and `//toggledebug` and similar entries with foregoing slashes are kept - those are commands

|Translation key|Explaination|Reference
| :- | :- | :-
| `tool.debug.lore.2` | Meta values are a Minecraft specific term | https://github.com/thebigsmileXD/MagicWE2/pull/137#discussion_r331998383
| `ui.brush.options.flags` | Flags means "adding options" | https://github.com/thebigsmileXD/MagicWE2/pull/150#discussion_r332669003
| `Biomes` | Biomes are a Minecraft specific term | https://minecraft.gamepedia.com/Biome
| `Chunks` | Chunks are a Minecraft specific term | https://minecraft.gamepedia.com/Chunk

## 💜 As always, enjoy Hacktoberfest!
Have fun and good luck with your 👕, Dan ❤
