Villagers now generate with random aptitudes for certain professions. When levelling those professions, provide the villager with a Tome of Aptitude to unlock extra trades! No more unfortunate accidents for librarians with bad enchantments or clerics with no ender pearls!
Future plans:
Special abilities for high-aptitude villagers, e.g. librarians upgrading all enchants on a book by 1 or rerolling them within same rarity.
Nitwit aptitudes: convert nitwit to a random profession with a uniquely high aptitude!
