- quote double quote properly by converting single double quote to

   double double quote.
 - quote all values when preparing csv strings from array to prevent
   from unexpected line-break or delimiter char.
 - use CR (carriage Return, \\r) to all replace LF (line feed, \\n)
   since excel seems prefer \\r over \\n.
