New mechanic to add veriety.

Player has 1 engineering team, that builds/sraps/repairs buildings. Team shoud travel across the map just like transport.

It will not allow players to instantly rebuild entire base, and early game will be much smoother.

Here might be some exceptions:

- Self-deployable buildings. Like farm right now. Quarry might be self-deployable.

- Some way to increase amount of engineering teams.

- Some HQ might have advantage. Second team or constructing without teams at all. Or constructing buildings, connected to HQ, without team. Repairing and scraping without team (robotics e.g.).

P.S. Inspired by little repair drone.
