Remove all the old references to "toy language"

This is a relic from the early development days in this repo. When I first started this repo, it was a clean-slate playground to test ideas for solving the road blocks I hit with my previous attempt at an org-mode parser. To keep things simple, I originally only had a very basic set of syntax rules that only vaguely looked similar to org-mode. Once I had things figured out, I kept developing in this repo, morphing it into a full org-mode parser. A couple of references to those early days still remained, and this patch should get rid of the last of them.
