A simple mod that allows you to modify the fuel value and pollution multiplier of items and fluids.

The default settings for this mod feature one actual change: Liquids like oil now have an energy value and pollution modifier, this only affects your game if you have a mod like Barrels O' Fuel or Simple Gas Boiler.

A note on the default settings for liquid fuels
Crude Oil:1MJ per unit, 150% polluition
Heavy Oil:1.5MJ per unit, 150% polluition
Light Oil : 1.2MJ per unit, 100% pollution
Petroleum: 0.9MJ per unit, 50% pollution

The following are supported explicitly: (Fuels from these are shown in the settings when you have the mod enabled/installed.)
Space Age
Wayward Seas
Boompuff Agriculture
Fluroflux: Stingfrond Agriculture
Flamethrower Fluid

The list of fuels is non-exhaustive, limited to things that are commonly used as fuel, if you want to modify something that isn't displayed, use the custom settings at the bottom of the mod settings for this mod.
The custom settings will require you to use the internal name of the item or fluid in question. Prototypes of type "item", "capsule" and "fluid" are supported. The format is a simple space-separated list: "one-thing=3MJ another-thing=500kJ"
The correct fuel value postfixes are kJ, MJ and GJ. Note that they're all upper case, except for the k in kJ, if you mess these up, Factorio will complain.
