Reorganize parts

My idea:
Fins, RCS, Gyroscopes - Control
Engines, Jet engines - Propulsion
Rotators, Motors, Pistons - Robotics
Cargo bay, Fairing - Payload
Wings, Fuel tanks, Struts, - Structural
Landing gear, Parachutes, Landing legs, Wheels - Ground
Command pod, Command chip, Chair, Astronaut(?) - Command
