Api updates

Hey, awesome project you have. This is the only wallpaper generator that I've been able to get working in quite a while. I did have to do a few things to get it working however, so I figured I'd send them back into the main repo. First is for kanji that you still have in your lesson queue, it doesn't have a stats attribute. The second is that at some point "enlightened" changed to "enlighten". With those two changes I was able to get a generated wall paper.

Thanks again!
