Scoviles - A measurement of Food Spiciness

[Trustworthy]

Without introducing a whole new system - why not expand on chemistry by adding this as a chem with several dosage stages?
Most of the chems seem to only have a non-overdose and overdose-stage ... there could be some in-between to flesh out the different positive and negative effects?

Could always give capsaicin(which all our spicy stuff already contains) have dosage specific effects to emulate this.
