Fixing issue #45 : Allow export/convert without header row Some minor fix.

Thanks for the Pull request!

The export button should not change self.csvConfig.

But I think there is a bug in -dataWithCSVConfig:. It checks self.csvConfig, instead of using the passed parameter config when checking whether to write the headers. Then it should work.
