C++ implemented code 1

Hello,

I firstly implemented a scene manager, one for a game scene and one for a menu scene. This will free up the my game from storing all the data, with spreading the data throughout different classes.

The game scene will hold all the data regarding the game, meanwhile the menu scene will hold all the data for the menus. In the menu scene it will have instructions and lobby to connect all the player. While the game scene will have all data for players, maps, buildings, score and currency.

Thank you for reading.
