Export current PositionList as CSV

[routeconverter]

I'd love to have CSV export, too. I'm planning this for years and there is a branch on github with first code: https://github.com/cpesch/RouteConverter/commits/csv

Help is appreciated.

Give me something to do

If you like... checkout the branch above and make a proposal or write a patch based on the first code fragments to implement reading and writing CSV files.
