Smart rotation while dragging underground pipes

[Zaspar]

When dragging belts, you can press r and the belt will rotate in the direction the mouse is in relation to the dragged belt segment. This can make building spaghetti through your base really fast and easy. Implement the same for underground pipes by automatically placing a single pipe, to connect the segment and continue with undergrounds going the new perpendicular direction, all by just pressing r while building.
