Create logic for games [big issue, needs to be splitted]

The backend must be able to handle multiple gamestates (connected to a lobby).

The backend must be able to get payload from clients (actions), and handle them accordingly.

The internal lobby-state will supply the backend with:

• Players
• Associated game (the game will supply currentTurn, terrain etc...)

The clients will send the following payloads:

• Movement
• Projectiles fired
• ExitGame

The backend will have to do the following:

• accept payload from players
• Check payload is legal and from correct user
• Calculate projectile-hits and update score
• Alert when its next players turn and send updated gamestate to both players
• Update highscore at the end of a game
