A bit of an architectural change before we progress further. Moved
player code into a shared PlayerBass class to elimnate some severe code
duplication while i was getting things working.
- Server can handle multiple clients simultaneously.
- Client can see other players in the game.
- Server broadcasts the game state to all clients.
- Client receives the game state and renders the other players.
- Server assigns a unique ID to each player.
- Client receives its player ID form the server.
- Server handles client disconnections.. Kinda... Server is ignoring
SIGPIPE signal.
- Server and client signals are non-blocking.
- Moved player objects off the stack and onto the heap.
