[Patroklos]

More Orbital componets to make stations and orbital facilites more diverse and useful. Maybe special city components you can put in Starbases (would be that big) that store population but lets the planet below use it for production. Orbital Cities.

Make larger ship classes require more than one type of facitliy to build it. An escort requires only a planetery space yard, but cruisers and up require an orbital one, and dreadnaughts require monstrous orbital space dock facilities.
