maj00r b8f040e6fd propagate template headers transitively, import Console where used
AnimModel.cpp reaches cParser through the simulation core, not a direct
import, so the previous pass missed it; the propagation now follows the
whole import closure. Train.cpp, drivermode.cpp and Globals.cpp call
Console:: inside _WIN32 guards without importing eu07.console - invisible
on Linux, where those blocks are skipped.
