Can't ignore solid-fuel

[ams2990]

Take any recipe that uses rocket-fuel as an ingredient (including rocket-fuel itself). solid-fuel should be hidable, but is not.

I guess it's because the calculator cannot be sure how it's being produced. It's being treated the same as a 'base' ingredient, like ore, coal, stone, and refined fluids, none of which can be ignored.

same problem with most fluids and sulfur. I'd rather be able to hide things that aren't 100% clear and have the program make assumptions that make some secondary information slightly off, than not be able to hide stuff at all. e.g. when trying to calculate in/out belts for battery production, I cannot be sure how many belts of iron plates I need for the battery factories themselves.

not to mention - when I hide stuff, where it comes from shouldn't affect electricity calculations anyway.
