Problem: Exporting to CSV in the list module is limited.

• When saving as CSV, only the displayed records are in the CSV. When people want data in a raw format like CSV, they don't want information in a paged view.

• When exporting to CSV, fields are not processed, so instead of the list of user groups in the fe users, we have a semicolon list "1,4,...". This is not really "WYSIWYG"

• When saving to CSV, control fields like CONTROL and _CLIPBOARD which are always empty, are also exported. Totally unneeded.

• The limit in the DB query is now set to the number of total records in the table when saving to CSV
• The data is processed before prepared for CSV as well
• the fields CLIPBOARD and CONTROL are excluded when saving as CSV.
