Modify GetPolygon() for coordinate option by etzh - 2013-08-14

It would be great if GetPolygon() had an option so that you could choose whether it looked up original or corrected coordinates. This would be very useful for challenge caches which usually state that the coordinates that count for Multi or Puzzle caches are the original coordinates..

Currently there is no option for this in GetPolygon. It uses current (i.e. corrected if there are any) coordinates.
