Make login form

Improvements for the command `make:auth` in order to create a form login.
Now, the `make:auth` command asks if the user wants an empty authenticator or a form login.
If "form login" is chosen, the user  is asked for the security controller name, and for the user class, if needed.
If the controller already exists, the command adds the login / logout methods in the existing controller.
