Implemented game launching API for the frontlib.
It is still buggy though, and not all game settings can be conveniently created/modified yet.
/*
* Sockets for TCP networking.
*
* This layer offers some functionality over what SDL_net offers directly: listening
* sockets (called acceptors here) can be bound to port 0, which will make them listen
* on a random unused port, if one can be found. To support this feature, you can also
* query the local port that an acceptor is listening on.
*
* Further, we support nonblocking reads here.
