Enchanter’s stuff

I decided not to make a unique texture for each enchantment. Instead, enchantments have textures that show an item that can be enchanted with them. The exceptions are treasure enchants, damage enchants (BoA, Sharpness and Smite, as they can enchant a sword, mace and axe) and some other enchants that are too cool to have a common icon.
Maximum-level enchantments have their own color, so you can easily find the best books in your chest.
I also slightly changed the textures of the bookshelves (for consistency with chiseled bookshelves), regular books (literally 3 pixels lol) and lapis lazuli (to make lapis lazuli really look like a magical resource).
