Adds the Acceptor and Client class.

The acceptor combines the endpoint and acceptor to reduce clutter in
NetworkHandler class.

The client will handle the connection for the network handler for every
separate client.

The networkhander now has a std::list of Client, to keep track and
ownership of all the Clients.
