//  Function:   HrRegisterFolderClass
//
//  Purpose:    Fix the registry values for the Shell entries under HKCR,
//              CLSID\{CLSID}. The code generated from the RGS script doesn't
//              support our replaceable params by default, so we'll fix
//              it up after the fact.
//
//  Arguments:
//      (none)
//
//  Returns:
//
