added classes for client and server state machine

- a client state machine consits out of a 'ClientState' (every state of the machine) and a 'ClientStateMachine' (every state, which consists out of states), the machine starts with the ClientAutomaton
- analog for server
- started to implement logic for the server, transition from 'Lobby' to 'GameState'
