IP and Port Representation

Small hurdle that I tried to tackle tonight is the representation of IP addresses and ports. There are at least 4 representations of each that will need to be dealt with regularly:

- ASCII (e.g. "127.0.0.1", "80")
- Host-byte-order integer, useful for ports (16777343, 80)
- Network-byte-order integer, used in raw packets (2130706433, 20480)
- Network-byte-order byte-string, used by "inet_aton" and the like. ('\x7f\x00\x00\x01', '\x00\x00\x00P')

So, the IP address and Port were encapsulated in classes. This should make dealing with them slightly easier.
