Added another example, this time using HTTP Basic Authentication method and posting to a BassRocket.com web service. Added new functioanlity into HTTPClient to enable easy adding of HTTP Basic Authentication headers and also improved the class by setting the showErrors() default value to TRUE to ensure that the class returns failed web service data back also as by default it was not returning the response body unless it recieved a vald 2xx HTTP status code thus stopping certain JSON based error hints from web services from being displayed.
