Duel, Arcs, Launcher Angles and Starved Reactor fit and place the Longinus
(thrusters, Core Power or MoveOnPro at (2,4), radiators relaid); the modes start
a Longinus (Settings.asset StartingHullName; the Aether multipliers leave it).
The drive's tests, its Steering Axis probe and its Brownout fixtures go with their
subject; ship_cc.py and the live-game checklist drop the drive and the hull.
The drive itself and the catalog records are deleted in the following commits.
