Differences are that the old IWebServiceRequest interface is renamed to IWebServiceRequestAsync
  and the new IWebServiceRequest2 interface to IWebServiceRequest.
  
  This new interface, although coded synchronous, but off-course allows game programmers 
  to call asset asset menthods using it asynchronously. This also allows usage with 
  both co-routines/yield() as well as async/await.
  
  The new interface also allows for non-standard verbs and can now be used easily for code like
  if (HealthCheck() && Login()) { <Communicate with the server> }
