With RAILWAYS, highway-like sectors double as rail. They need to be at least 5% efficient to be operational, and then they additionally extend rail into adjacent sectors that are at least 60% efficient. New opt_RAILWAYS, SCT_HAS_RAIL(), sct_rail_track(). Update sector_mcost(), bp_neighbors(), lnd_mar_one_sector() for RAILWAYS mobility rules. Update sinfra(), spyline(), satdisp_sect() to show rail track instead of rail infrastructure for RAILWAYS. New virtual sector selector track, implemented by nsc_sct_track().
