[META] Overhaul the unlock system

[MasterEnderman]

Random Collection of notes from Discord

{
  "unlock": {
    "event": "breakBlock",
    "trigger": "minecraft:stone"
  }
}

ideally players would spawn with the book, and only one category unlocked (an intro category)
there would also only be one entry unlocked, and reading to the end of that entry unlocks the next
and so on, until they finish the last entry, which then unlocks a few categories
and from there entries and categories would be unlocked based on actions like so

so entering a new biome? unlocks category
picking up a certain item? unlocks entry

• break block
• use item
• visit biome
• visit dimension
• visit location
• kill entity
• pickup item?
• craft item?
