Remove pippo-spring module from next major version of Pippo

[decebals]

The idea is that I used with success another, more natural approach.
First of all I injected the needed services directly in Controller class:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import ro.pippo.controller.Controller;
import ro.pippo.controller.Path;

@Path("/clients")
@Component
public class ClientController extends Controller {

 @Autowired
 private SubscriptionService subscriptionService;

 @Autowired
 private ClientService clientService;

 // GET, POST methods

}

Add all controllers in Application after they were collected by Spring:

import org.springframework.stereotype.Component;
import ro.pippo.controller.ControllerApplication;

@Component
public class MyApplication extends ControllerApplication {

 @Autowired
 private List<? extends Controller> controllers;

 @Override
 protected void onInit() {
 addControllers(controllers.toArray(new Controller[controllers.size()]));
 }

}

The content of this issue is related somehow with #538.

Also related to Spring support in Pippo, see below how you can use the Pippo hot reload mechanism when Spring is used for DI:

public class Launcher {

 public static void main(String[] args) {
 Pippo pippo = new Pippo() {

 @Override
 protected Application createReloadableApplication() {
 return new AnnotationConfigApplicationContext(SpringConfiguration.class).getBean(Application.class);
 }

 };
 pippo.start();
 }

}

It would be nice to note in some way what we have to create / update in the documentation. Pippo has a lot of cool stuff!

I will update the documentation. Yes, Pippo has a lot of cool stuff that are not documented and it is easy to add some new ones.
