Fixed bug; When importing, LOVD could have used the wrong data for checking the panelid, fatherid and motherid links.
- Links to records in the file should take preference over links with database entries, instead of the other way around.
- Links to the own ID aren't allowed, so stop throwing additional, confusing, error messages.
- The panel size was checked only when the Individual/Gender column was active.
- Also, checking for the Individual/Gender column happened once or twice per data row, instead of once per import.
