ESRI to OGR Parameter Mapping Issues

[hgrabows@…]

There are many cases where the projection parameters between ESRI and OGR differ in name. There are two included examples of where this occurs. The second one, the World Mercator projection, has an additional problem where "Standard_Parallel_1" is used by ESRI but isn't considered a valid parameter by OGR. Therefore this projection fails to validate correctly.

This should be reviewed before the GDAL 1.2.0 release.
