[talk-au] Download a route

[John Smith]

I've been playing with sorting nodes by way, then the order they
appear in the way:

http://map-data.bigtincan.com/route2gpx/v2.php?routeid=124080

This gpx file can be loaded in JOSM and shows how the ordering can be
screwed up and in turn screw up the routing I guess.

I've manually been ording ways in the relation to try and fix it, but
I might need to check if the points between the ways are
closer/further to the previous way and reverse the order the nodes are
spat out in that way...
