This pull request follows #508, by consisting of the graphical part of the notification-based feedback system.
It adds a new interface, Notification, and two new classes, NotificationHandler and ToastNotification.
A single test file effectively test both classes (they work together).
The NotificationHandler is a Singleton whose spawn() method can be called from anywhere to display a Toast notification on the screen. A ToastNotification object can be even more customized by using the detailed constructor of the class.
Every class implementing the Notification interface can be used with the NotificationHandler.
