Let Me Despawn

Added a config : config/letmedespawn.json

• "/lmd reload" to reload the config ingame after editing.
• "/lmd add <mobName>" to add mobs to the config
• "/lmd remove <mobName>" to remove mobs from the config.

All the commands update the mob list in realtime you dont need to run "/lmd reload" or restart the game after adding or removing mobs. "/lmd reload" is there incase you want to edit the config outside the game.

Fixed some issues, thank you components, very cool.
