Netboa

I've started the total re-write of my asynchronous network library Miniboa. The new code, in addition to being cleaner, is different in several ways.

What's New

• No longer Telnet-centric; my aim is to keep connections generic and wrap them in protocol handlers.
• Services; you can now run multiple services under a single server. Each service listens on a different port and can have unique protocols and events.
  
• Added hooks for coroutine-based, character-at-a-time protocol handlers.
• No longer line-based; the new API has get_ch() to get one character or get_input() to retrieve the entire input buffer. This is support users that want to write features like text editors and command completion.
  
• New event; on_input() that is called when the data is received from the client.
• When run under Linux, it uses the Epoll API introduced in Linux kernel 2.5.44. All other platforms user Select().

I kept the server polled from within the user's game loop. I know that event and callback driven designs are more efficient, but I really like the approachability of that pattern. It can be hard to think in terms of callbacks.
