Station order in the th2 file appears random

[AndrewAkinson]

When working with the th2 file the stations appear to be in a random order. This is very inconvenient for adding more than one scrap to the file, as the stations need to be in the right scrap. If the stations were ordered in the same order as taken (usually numerically) then it would be simply a case of adding a scrap end scrap round the right groups of station. Currently the stations all have to be moved into the correct scrap, which is very hard on the Therion interface. I ended up reordering the stations in a text editor.
