Please update the 'baked' cheatsheet

Hello, I love using https://danielkeep.github.io/itercheat_baked.html as a reference, but at this point it's pretty dated. It's still useful but as time goes on I worry that I may overlook options that exist today but didn't when the cheatsheet was made.

I do find it useful and give out references to it often on irc. I hope this is sufficient encouragement to repay the work! :)

Thanks
