* Denmark clinch first World Cup * France, China and U.S. share second * Defending champions Australia share ninth (Adds detail, quotes) MELBOURNE, Nov 27 (Reuters) - Soren Kjeldsen and Thorbjorn Olesen kept their nerve and shot a six-under-par 66 in the final round fourballs to give Denmark a first World Cup of Golf triumph by four strokes at Kingston Heath on Sunday.
