Add recipe item hints to craftRecipe in skills.js

[JurassikLizard]

Added a couple lines in skills.js that hint the model. Can tell the model that item doesn't have crafting recipe/isn't real item, or hints the required amounts of materials to execute the craft.

In my experience, this helps stupider models not get stuck in loops, such as collecting wood_logs over and over when it just needs to craft sticks.
