Feature: Traveller's Guidebook

[OscarPayn]

Need to figure out how much of the initial 1.12 design we want to carry over (I'm leaning towards most of it really)
For discovery content like the bestiary and locations etc we need to sort out the different ways you can unlock/obtain info (guidebook page items, mob interactions, landmark proximity, biome proximity etc)
I'd also like to have a page for advancements that allows us to by default have a larger advancement screen, but still extend off the vanilla system
I'd also like a built-in map but that isn't necessary for 0.1.0 imo
