Add Controller helper methods for StatusCode(int)/StatusCode(int,object)

[rynowak]

I feel like I've answered questions about ObjectResult + status code a million times by now. We should make this more visible.

@rynowak by this do you mean something like:

[NonAction]
public virtual StatusCodeResult StatusCode(int statusCode)
{
    return new StatusCodeResult(statusCode);
}

[NonAction]
public virtual ObjectResult StatusCode(int statusCode, object value)
{
    var result = new ObjectResult(value);
    result.StatusCode = statusCode;

    return result;
}
