The name 'mineaft:stone' should be 'minecraft:stone'

It's a super expensive recipe for dirt, so not that big of a deal lol. Not any special dirt, just minecraft:dirt.

Probably put it there when I was testing the JSON recipe format to transition recipes to.

Either way, fixed it in the code for if I ever release another file any time soon.

To answer the when question, I have just released v1.5 which fixes this bug and #34 , code has just been updated to github
