Subject: [PATCH] Support Overriding World Seeds
Allows you to add to paper.yml
seed-overrides:
world_name: some seed value
This will ignore every where a seed is set/created/loaded and force
a world to use the specified seed.
This seed will end up being saved to the world data file, so it is
a permanent change in that it won't go back if you remove it from paper.yml
