Opus (Guidebooks)

New Features

• New Book of Books that holds every Opus guide in your pack in a single inventory slot. Craft it with a book and a chest. It is inspired by the Akashic Tome mod, and works the same way: combine it with Opus books in a crafting grid to add them (duplicates are fine), right-click it to pick a guide from a menu, punch the air to turn the guide back into the Book of Books, and sneak and drop a guide to take it out of the set. Pack authors can let it hold other mods' guidebooks by adding those items to the new opus:book_of_books_storable item tag, which is empty by default.
• New Opus advancement tab. Crafting a Book of Books for the first time grants the hidden "Bookception", and carrying one that holds 10 or more guides grants the hidden challenge "Magnum Opus".
