Final clean-up for vvexport/vvimport - strips whitespace before exporting, converts tabs and newlines to {tab} and {newline}, strips html tags from human readable first line, icons aligned left in browse menu, import returns user to browse page. Testing shows export/import/export produces identical match indicating no data loss.
