Business Layer; ISWebService is obsolete; Replaced with ISHttpClient

The ISWebService class in the business layer that is used for executing web request has been marked as obsolete. This is due to the underlying Microsoft class System.Net.WebRequest being made obsolete.

There is a new ISHttpClient class in the business layer that uses the recommended System.Net.Http.HttpClient class for making web requests.

NOTE: Scripts will produce warnings if ISWebService is used.
