Factorio: Introduce progressive-fluid-handling

[Toby-Lawrance]

What is this fixing or adding?

progressive-train-network currently has the order of: railway (trains and rails and cargo wagons) -> fluid-wagon (fluid wagons) -> automated-rail-transportation (train-stops) -> rail-signals (Chain and Standard Rail signals) -> braking-force-1-7 (Trains slow down faster)

This adds a new manual progressive chain named "progressive-fluid-handling"

progressive-fluid-handling has two components: fluid-handling -> fluid-wagon

progressive-train-network is shortened in chain by one to: railway -> automated-rail-transportation -> rail-signals -> braking-force-1-7

How was this tested?

Tested with a short 2 person game to verify hints worked. "fluid-handling" was not left over separate. technologies were awarded in the correct order and that no errors were presented.

If this makes graphical changes, please attach screenshots.
