Adds more pipe connections to allow assembling machines (including chem plants, oil-refineries (toggleable by settings)) to pass through fluids, like electric miners.
doesnt seem to work on lubricant plants, when u place them close to each other 1:1. If you have a gap between them, or dont place BOTH inputs together, it works
Incidentally - this is resolved in 0.18.31 Input fluid box with connection set to output or input-output will not have volume forced down by recipe fluid ingredient amount.
Version 0.1.14 of APP adjusts base_area to suit so that chem-plants don't store a large volume of fluid.
