Feature
Add .env and environment handling for game variables.
Ideal solution or implementation
Each variables for the client must be prefixed with NANOFORGE_CLIENT_
Each variables for the server must be prefixed with NANOFORGE_SERVER_
The cli will parse the variables and remove the CLIENT_ and SERVER_ part in the name before put in the env of the loader when started.
