Title: Added support for authenticating a request

```c#
var request = new FakeHttpRequest();
Console.WriteLine(request.IsAuthenticated); //False: previously a NotImplementedException
request.SetAuthenticated(true);
Console.WriteLine(request.IsAuthenticated); //True
```

Also extended the `FakeHttpContext.Authenticate()` extension method:

```c#
var context = new FakeHttpContext();
context.Authenticate();
Console.WriteLine(context.Request.IsAuthenticated); //True
```
