Adds 5 new tiers user scalable assembly machines, chemical plants, oil refineries and smelters, and 3 tiers of centrifuges. Graphics provided by Skunkduster.
The advanced chemical plants have only 2 recipes in them. They still say "work for 8 items recipes" but the recipe item limit has not been there since 0.16
I rechecked the code, and the ingredient count for the Mark 2 is 6, while the ingredient count Mark 3, 4, 5, and 6, is 8. These upper limits are set if the player wants to have a mod from another mod developer who does have an item with a recipe that needs more then 4 components.
