Update the line names

[rachaelcodes]

here is a list of the line ids that the tfl api uses - can we update our HTML form to return these? (this might mean we don't need the parsing name function in logic.js and have to cut out a couple of lines like TFL rail)

exports.lines = {

  | "bakerloo": "Bakerloo",
  | "central": "Central",
  | "circle": "Circle",
  | "district": "District",
  | "hammersmith-city": "Hammersmith & City",
  | "jubilee": "Jubilee",
  | "metropolitan": "Metropolitan",
  | "northern": "Northern",
  | "piccadilly": "Piccadilly",
  | "victoria": "Victoria",
  | "waterloo-city": "Waterloo & City"
  | };
