Added a GetDynamicMember Method in the SuperSimpleViewEngine

SuperSimpleViewEngine was unable to render properly the TextResourceFinder, for example

```c#
Get["/"] = parameters => {
    var m = new { Text = this.Text };
    return View["Index", m];
};
```

with

```html
<h3>"@Model.Text.Text.Greeting"</h3>
```

Will throw an InternalException because SSVE didn't know how to get the value from a DynamicObject.

Just created a method to get the value correctly `GetDynamicMember` in SSVE, and it works :)

And I just copied the Nancy.Demo.Razor.Localization and "reformated" with SSVE.
