Title: TextResponse and AsText

This is similar to the asp.net mvc's `ContentResult`. It makes returning plain text easier. I named it TextResponse rather then ContentResponse coz I think Text is more precise.

I have created a new response called TextResponse.

```csharp
var response = new TextRespone("sample text");
response = new TextResponse("sample text", "text/cache-manifest");
```

I have also added response formatter extension methods.

```csharp
return Response.AsText("sample text");
return Response.AsText("sample text", "text/cache-manifest");
```
