Early game: remove the requirement to unload the harbor

This is a really minor complaint: To unload the harbor at the beginning, I have to build storage space. I don't build storage space, because on hard mode storage space isn't a good use of my construction parts early on.
At some point I have to make that decision: if I want to get access to the copper and the vehicle parts (mostly) that my ship returns from its voyages now, I need to build storage space for rubber and other stuff that was stored in the harbor since the beginning.
I postpone that quite far back, because - together with the tutorial rewards - building e.g. the copper supply chain first is the better strategy. But it feels stupid to have those resources waiting until I finally have the abundance of construction parts to build the storage units.
