indicate that a sector has canal capability. Add canal determination
logic to shp_check_nav(). Update sector_navigation[] with new
canal navigation enum. Use shp_check_nav() to determine the

lchr_ca's item selector was incorrect and worked only by accident.
Add M_CANAL flag to indicate which ships can navigate a canal
in a big city. Remove the hard code values for canal from
shp_nav_one_sector() for which ships can navigate a canal.
Set M_CANAL flag in ship_chr_flags[] to match the hard
coding in shp_nav_one_sector().
Update Ship-types.t with new canal flag.
Update Sector-types.t to indicate that cities have canals.
