Bukkit

- Updated to Paper 1.21.3

- Recipes are now unlocked via recipe book rather than automatically on join. (Old system of giving them on join can be re-enabled via config.)

- Chaos Block loot tables rebalanced and spawn rates adjusted.

- Chaos Block spawn rates can now be configured in the config file.

- Laser Rifle now more performant and less likely to cause crashes/error messages.

- Force Bomb now handles falling block IDs correctly for post-1.8 blocks. Physics still experimental.

- Re-introduced the ability to create your own items via custom configuration files. Feature currently still experimental - next update will stabilize this and add new enchantments such as Frostwalker or Swift Sneak that didn't exist when the legacy code was written.
