Better Enchanting

Rewrite how enchanted books are handeled in loot chest :

• All enchanted books will be automaticly replaced by the ingredients of each individual enchantments of the book upon generation.
• If the enchantment is not present on the config (i.e. moded enchants not configured), a bottle of experience will be added instead.
• If the ingredient generated is not an ingredient for the max level (not an essence for all vaninila enchants), a random amount of the item is added, otherwise, just one.

This update should be a step closer to full compatibility with other mods adding enchantments.
