Move books between lists

Currently, the plugin filters books to just the ones in the user's currently reading list, to avoid creating a situation where a book has progress but is still marked as "want to read". We can fix this by querying the user's lists, and then updating the record's associated list type and list at:// URI.

This would also allow us to safely query for all books in the user's account, and enable the plugin to mark books as "done".
