Extended Starcounter.ErrorCodes project to support automatic generation of the C# API to error code constants during build.
Factored the path to the produced error code compiler executable into a MsBuild property.
Added the scerrres project and redesigned how the resource library is built. Also cleaned up all solution platform solutions we dont use from the solution file.
Added version of scerrres project that build 32-bit outputs, to be able to consume error code formats in 32-bit processes as well.
