[WIP] Recipe reference rework

- [x] Conceal book details until player has read the book for one cycle.
- [x] Allow player to craft a recipe using a nearby book as a reference.
- [x] Delete oxford comma with extreme prejudice.
- [x] Give player chance to learn/memorize recipe when making it using a book as a reference.
  - [ ] Tweak chance to learn, any suggestions?
- [ ] Remove/lower chance to memorize recipe from reading book. (up for discussion)
