Flights

• I have added a new field in the FlightStats entity called “lowestPriceOneStop”
• Amend the Kayak scrape to include 1-Stop flights as well as Direct-only (currently the search specifies Direct-flights only) and store 2 prices for each route/date…. the best Direct flight price in the field “lowestPrice” and the best 1-stop price in “lowestPriceOneStop”
• I have adapted the calendarindex twig and the controller to show the choice of the user (button at the top to toggle between showing both Direct and Direct+1-stop)
• Don't wait for each scrape to update the screen.  Update after each scrape (ie per day/route)
