WKT to EPSG conversion fails for spherical mercator coordinate system

Description
This issue manifested itself in the failure of the redlining tool in flexible web layouts based on maps using the spherical mercator coordinate system, as used by popular commercial mapping sites such as Google Maps, Bing and Yahoo.
The coordinate system API failed to convert the WKT string defining the coordinate system of the map to its corresponding EPSG code, as required by OpenLayers. The result was that redlining features could be created and saved, but when they were loaded back in they were treated as LL84 coordinates, and didn't show up on the map.
