WaniKani Lesson Ordering II (obsolete, does not work)

NOTE – October 3, 2021 – this script is no longer working due to recent changes to the WaniKani website. I’m happy that so many people used and loved this script since 2014, but I’ll no longer be able to support it. Instead, please try one of the newer reordering scripts, such as Reorder Ultimate II or WaniKani Lesson Filter. Thank you, and がんばれ!
