* Replaces the shuttle_controller and shuttle process with the shuttles subsystem. Instead of docking ports being initialized by the game ticker, its part of the StonedMC Master init order.
* The main advantage of this is control over the initialization order, as well as letting Master be aware of CPU we're using up with shuttle processing.
* By being part of the Master init order, we reduce the uncertainty about "are objects initialized yet?" which is nice, since shuttle docks break if machines aren't finished initializing!
