Use `System.Net.Http` instead of `Windows.Web.Http`

In Windows 10, the implementation of the System.Net.Http API for UWP has been changed to layer it on top of Windows.Web.Http and the WinINet HTTP stack of Windows.
System.Net.Http seems more general and more widely used. We should change our implementation to use the "new" API.

HTTP/2 Support (Windows 10)
HTTP/2 is a new version of the HTTP protocol that provides much better connection utilization (fewer round-trips between client and server), resulting in lower latency web page loading for users. Web pages (as opposed to services) benefit the most from HTTP/2, since the protocol optimizes for multiple artifacts being requested as part of a single experience. HTTP/2 support has been added to ASP.NET in the .NET Framework 4.6. Because networking functionality exists at multiple layers, new features were required in Windows, in IIS, and in ASP.NET to enable HTTP/2. You must be running on Windows 10 to use HTTP/2 with ASP.NET.
HTTP/2 is also supported and on by default for Windows 10 Universal Windows Platform (UWP) apps that use the System.Net.Http.HttpClient API.

System.Net.Http is implemented atop of Windows.Web.Http
