Allow Multiple Recipe Unlock Triggers

I think the recipe book often gets a bit crowded early on in the game because there is a single trigger for unlocking a recipe. I think it would be nice to have multiple triggers.

For example, instead of learning how to craft every boat from every wood type when you get in water, I think only being able to see the recipe for any plank type you've already discovered.

Another example is the harness recipe being visible even if the player has never been to the Nether.
