This update adds a new /clearbook command which removes all text, author, generation and title from a writable (unsigned) book. Use it if you want to start again, and don't want to manually erase each character.

If you use writable (un-signed) books as payment method, books containing text will now be ignored. You no longer need to worry about your work in progress book being lost when payment is taken.

A bug where un-signing a stack of signed books would return one un-signed book has been fixed.
