I think it's not so hard. Is it really neccessary that client attributes
coincides with the savegame *exactly*? I don't think so.

The agent data, as of now, are user input. What happens if they don't
fit, e.g. a city doesn't exist any more? They can't be applied. The
client could be somewhat fault-tolerant about this. The worst case
is the user has to redo some agent settings. This doesn't harm,
as long as I can control the saving of the client attributes.

That is why I'd think savename + year is unique enough.

If we get CS-Integration (after the release) this could be nicely
automated (Server save and client save).
