Outpost mining

Rather than having dirty miners inside the pure temple of science they now have a new little outpost for their ore offloading needs.
Larger than originally intended but the conveyor belt needed a non-magical power source and it felt odd to pull a power cable from the research outpost.

Also took the opportunity to synchronize the direction of the input and disposal feed conveyor belts over at the west mining outpost.
