Make the captain able to tweak the buildings' in/ot ports

To provide another level of customization, the player should be able to fully customize where on a building are the in and out ports. On the 3 axes, meaning you could change the side and place of a port on the grid, but also bring them up or down, like on the slag crusher for example.

Of course, each new variation f a building would need research, or maybe ressources sent to a specialized "industrial building engineering" building that would need a tech to be researched first.
Then, each time the player builds a variation of a standard building, the building cost might be a bit higher, or not...

That would allow for much deeper optimization of factories complex.

That would cause a problem with the "blueprint" feature, since a specific blueprint might need a tweaked factory, wich would need to be included somehow in the blueprint and then be researched by the player importing the blueprint.
