New feature: Rating Machine

I've made a handy page that feeds you book after book you've haven't rated yet, so you can rate them.

https://www.librarything.com/ratingmachine.php

You can skip, "never ask again" and, with the cog, restrict it from giving you books in certain collections. (By default, wishlist collections are not included.)

It's a good way to get a lot of rating done.

Let me know what you think!
