In case you wondered about the Internal Errors: the Waypoints and Images 
links are deliberately not working. I have not added verification of the 
uploaded data yet. Therefore, I disabled the methods.

Yes, that is a good idea. At the moment, the merge preview basically 
shows the original tags; it only strips the naptan: prefix.
The way different tags are handled can easily be changed if needed. I 
have not implemented any particular suggestions that arose from the 
public transport tagging scheme yet. So, once decisions have been made 
there the editor can be updated. I also need to add a method to handle 
tags which are not part of the tagging scheme (discarding them silently 
is probably not an option).

> Also, what do the colours mean?

blue = Naptan stop (no highway=bus_stop but a naptan:AtcoCode tag)
yellow = plain OSM stop (highway=bus_stop but no naptan:AtcoCode tag)
orange = Merged stop (highway=bus_stop and naptan:AtcoCode, but is still
          unverified or has no shelter tag set*)
green = Merged and verified stop

* I do not remember off the top of my head if there is another rule. I 
think we discussed something about route tags on the mailing list. I 
need to check the code to provide reliable information.
