Updated to Minecraft 1.20.4

Changes: https://github.com/leothawne/TheDoctorReborn/commit/d62ef88a02c5a2d342a25611098e12e497fb7896

- Removed custom blocks and items ( /reborn recipes e /rebornadmin give will not work anymore!);

- Removed teleport feature between worlds;

- Removed /reborn home feature;

- Removed unused code;

- Removed the boring messages on the console;

- Updated database (tdr.db).

If you intend to migrate from any other version to 0.3.0, I recommend you to delete your current tdr.db file and let the plugin create a new database file.



After thinking a lot, I decided to make this plugin a (Doctor Who) regeneration feature only. I'm going to bring a new and more stable regeneration API to the next versions. I hope you enjoy this version and the next ones! <3

Changelog:
+ Fixed 'no permission to die' error (before, players without TheDoctorReborn.regenerate could not die).
- Removed TDR Worlds.
- Removed Music Player.
- Nautic Pickaxe can easily break only ores inside water.
- Removed all internal and external dependencies.
- Removed ingame support ('/reborn support').
+ '/reborn support' changed to '/reborn contact'.
+ Added new 'check for updates' system.
+ Added new options into config.yml.

Moved from Java 9+ to Java 8+ instead for more compatibility.

First stable version released.
