Expose the route-path of leg to Nasal.

Browse source 
In advance of converting the Map and NavDisplay to use the canvas, expose the full route-path vector for each flight plan leg, as a vector on the leg. Use leg.path() to get this.

E.g.:

var fp = flightplan();
for (var i=0; i<fp.getPlanSize(); i += 1)
{
  var leg = fp.getWP(i);
  debug.dump(leg.path());
}
