Adds a configuration file that allows you to add or remove fluids that can be used as fuel for the Aero Engine.

To add a fuel type, simply add its fluid ID to the allowed_fuels list. Make sure to add a comma after each fluid ID when adding multiple fluids:

allowed_fuels = [ "tfmg:kerosene", "examplemod:examplefluid" ]

To remove a fuel, simply delete its fluid ID from the list.

In default you can only use TFMG Kerosin as fuel.
