Book & Quill - Initial Commit

Implement Book & Quill:
- IUIScene_WritingBookMenu and UIScene_BookAndQuillMenu for UI
- Edited UIControl_Label to add direct editing (quite hardcoded to my needs right now)
- Reimplement scrapped custom payload packets for books and signing
- Other misc changes

TODO:
- Coloured and scambled text
- Book copying
- Clean up code
