Vars
addiction_types	Assoc list with key type of addiction this reagent feeds, and value amount of addiction points added per unit of reagent metabolzied (which means * REAGENTS_METABOLISM every life())
burning_temperature	Thermodynamic vars How hot this reagent burns when it's on fire - null means it can't burn
burning_volume	How much is consumed when it is burnt per second

color	color it looks in containers etc
creation_purity	the purity of the reagent on creation (i.e. when it's added to a mob and it's purity split it into 2 chems; the purity of the resultant chems are kept as 1, this tracks what the purity was before that)
current_cycle	increments everytime on_mob_life is called
data	Special data associated with the reagent that will be passed on upon transfer to a new holder.
description	nor do they have descriptions
failed_chem	what chem is made at the end of a reaction IF the purity is below the recipies purity_min at the END of a reaction only

glass_desc	desc applied to glasses with this reagent
glass_icon_state	Otherwise just sets the icon to a normal glass with the mixture of the reagents in the glass.
glass_name	use for specialty drinks.
glass_price	The amount a robot will pay for a glass of this (20 units but can be higher if you pour more, be frugal!)
harmful	is it bad for you? Currently only used for borghypo. C2s and Toxins have it TRUE by default.
holder	reagent holder this belongs to

inverse_chem	What chem is metabolised when purity is below inverse_chem_val
inverse_chem_val	If the impurity is below 0.5, replace ALL of the chem with inverse_chem upon metabolising
mass	The molar mass of the reagent - if you're adding a reagent that doesn't have a recipe, just add a random number between 10 - 800. Higher numbers are "harder" but it's mostly arbitary.
