Adds a reactor made with Iskallium and Steel Casing.
You find Iskallium Ore generated in the world. Mining it yields Iskallium Essence. The essence is used to craft Iskallium Blocks, as well as Steel casing, Iskallium Glass, Reactor power tap and Reactor controller.
A box needs to be built using steel casing on the corners, top and bottom, Iskallium blocks in the center and Iskallium glass on the sides.
The reactor will output 160 rf/t per every Iskallium block inside.
