RequestLogFeature doesn''t 404/403

The Request Logger was only meant for Service Requests but I’ve added support for other ServiceStack Requests in this commit which is available from v4.5.13 that’s now available on MyGet.

After short-circuited requests have closed the AppHost.OnEndRequest() will be called which you can override or register a AppHost.OnEndRequestCallbacks to register a delegate instead.

Please let me know if it adds the required logging.
