TRV Cobra-class Corvette Mk.II Model 1

A fairly large update to the Cobra:

• Added four Trident-ised Hornet AMS turrets, based on the Hornet from MeRobo's Turret Expansion Pack 1;
• Removed the USD docks and doors;
• Relocated the main entrance to behind the bridge module;
• Added a single hanging docker at the bottom front of the ship.

These changes are intended to allow the Cobra to function better as a deployable drone ship, since its original purpose was to be a drone deployed from Exodus-class battleships.

• Stripped all systems, added basic temporary systems to allow it to move
• Upgraded the exterior appearance slightly; updated to our new standard of finish.
• Added logic-controlled flashing navigation lights, and a button in the cockpit to restart their logic clock.
