Log:
Fixes #1320 - WKT to EPSG conversion fails for spherical mercator coordinate system

This submission modifies the coordinate system API method MgCoordinateSystemFactory::ConvertWktToEpsgCode to use MgCoordinateSystemWktFlavor::Unknown instead of MgCoordinateSystemWktFlavor::Ogc, which allows it to support more WKT flavors than just OGC, and allows it successfully to convert the WKT string currently used for the commercial mapping coordinate system used by Google Maps, Bing etc.
