TRV Xyphos-class Light Frigate Mk.II Model 1

This update is a fairly big external update and remaster of my premier light frigate:

• Added twin fusion missile launchers in the forward trench, with the associated details to match;
• Added visible reactor vents in the rear trench (built by Plaz);
• Cleaned up the spine leading from the bridge to the engine armour plate, it is no longer bumpy;
• Added two Trident-ised Hornet AMS turrets, based on the Hornet from MeRobo's Turret Expansion Pack 1;
• Misc exterior cleaning up courtesy of Plaz and MeRobo
