Choose column separator in Exports

[Bangaltar112]

When we export modules containing text-formatted line items and we choose csv or txt format, the column separator is automatically forced on 'comma'. If the text within the line item contains any comma in its body, it will shift the following columns and damage the whole file. 

It would be great to be able to choose the column separator when we select csv or txt in the export setup.

This would be a massive help for europeans dealing with the rest of the world and us dealing with the europeans.

The decimal/thousands separators should also be allowed to be set manually
