Ferries go wrong

[dracos]

Various different problems it seems:
http://split.traintimes.org.uk/BSK/RYD/n/10:00/14:00 - £0 journey
http://split.traintimes.org.uk/BSK/XRD/n/10:00/14:00 - invalid destination
http://split.traintimes.org.uk/BSK/YMH/n/10:00/14:00 - 500 Internal Server Error
http://split.traintimes.org.uk/BSK/WTW/n/15:10 - £0 journey

XRD isn't included because by default I've excluded anything starting with X. I think I've fixed the 500 error, changing it to another £0 journey; I think those are because fare ferries don't seem to be included in my generated fare data files, might be due to the NSD.
