The simulator hangs end signals only on a last vehicle with coupler 0; every
new car came with 3 and the pass that couples neighbours never touched the
last one, nor did taking a car off the end. The coupler editor says so for
the last vehicle.
Keeps the old starter's starter.batterydefault key and its three states. The
setting wins over the depot checkbox, which greys out and says so while an
override is in force.
It was a global preference that rewrote the trainset speed at launch, while what
it really sets is whether this consist starts prepared or cold. Now a checkbox in
the consist-scope section, acting on the consist being edited.
The number editor was pinned to the unit's first car, so every vehicle in a
multiple unit shared one number. Removing a vehicle only moved the highlight,
leaving the starting vehicle and the panels on the deleted one. Drops the tab
strip around the single configuration panel and shortens the consist row when
the thumbnails are small.
VehicleDatabase becomes VehicleCatalog, Physics becomes VehiclePhysics, and the
textures.txt and .fiz parsers move to Infrastructure. GameLibrary replaces the
GameData singleton.
