The export_csv_names extension doesn't handle Multilinks. Things like 
keywords show up as something like [8,9].

I have a fix for this in the attached file. Feel free to modify it, as 
long as it is an improvement.

Perhaps this could be a replacement for the file in:

Tom,
thanks for your report and the suggested improvement!

I think we need someone to test this with the current "tip" version
of roundup and then commit it to the core system it some way
as the export function from the webinterface is also affected.
However it may be that we need to support both versions of how
to export to csv.
