Skjeggegubben added ways to change the color of sheep and change the age of animals.


[Red-exe-Engineer](https://github.com/Red-exe-Engineer) fixed the entity ids, Entity classes, and Sheep class, and I added `entity.getEntities` and `entity.getAllEntities`.

Thanks to [Red-exe-Engineer](https://github.com/Red-exe-Engineer) `reborn.getVersion`, `reborn.getFeature`, `events.chat.posts`, and `events.chat.size` have been added.

Add basic entity spawning.

- Fixed bug with causing args to be cut off at the first left parenthesis.
- Fixed bug in `world.getBlocks` and `custom.getBlocks3D` causing them to target the wrong position.
- Added tests.
- Improved docs.
- Many breaking API changes.
- Many internal changes.
- Added `custom.player.getHealth`, `custom.player.setHealth`, `custom.player.closeGUI`, and `custom.player.getGamemode`.

This update adds RaspberryJuice's `getBlocks` feature along with a custom `getBlocks3D` feature so help preserve the 3D structure.

This version is also the first 2.4 compatible version.
