Tooltip for raw meat/variable materials

[Aethyr]

I'm already fallen in love with those new tooltips, they are really amazing and I've at least halved my visit to the wiki thanks to them.

Given that, I feel that this could be an opportunity to make the process of craft food with variable materials easier. I don't know exactly how can be implemented the contribute of variable materials to the final object, but maybe could be enough a simple "+1 const" over hedgehog raw meat when you are crafting roasted meat, for example.

Problem being that the effects are dependent on what they are applied to.
