Solution for exercise 13:

edited another state in the server and client, added the rocket, added the 'Shell.java' and 'ShellControl.java'
edited the logic for the states and 3 messages for the server client comunication, edited the 'SeaSynchronizer' and ShipMapSynchronizer', so that the animations will be displayed, added the sound for the rocket
