0006195: Import from pro-gen. Fix citations and sources. Also other fixes: Attach SOUR TEXT as note on citation. Ensure gramps_ids are not duplicated (change map record so it maps from Pro-Gen ID to handle), and format gramps_id according to the user's preference setting. Store 'aktenr' as REFN attribute or data. Store TITL (and _TITL2 and _TITL3) as comma separated Title. Store patronymic correctly. Prevent duplication of Baptism source text. Store RESI event for person address. Store family 'Relatie code' (FAM REFN/FAM CODE) as REFN. Note testing is limited by availability of test data.
