Blåhaj

This is a minor update to Blåhaj Mod. No new content has been added.

Made it so you can now use Fabric Loader to play with Blåhaj Mod. Fabric Loader compatibility is merely a secondary goal and will may not be a mainstay. This does not mean a commitment to Fabric compatibility, I'm merely seizing the opportunity to support it while supporting it is still little effort.
