* Added the automatic cleaning/pruning code to weed out entries that are probably disconnected.
* Added 'imcwhois <player>' command. Still needs some sanitizing on the outgoing string.
* Added the beginnings of a -reply packet handler through reply_listener.py.
* Fleshed out a few more packets in packets.py.
Next up: Make the ANSI system a little more modular. Create a class for ANSI tables so developers can pick and choose different tables on their own, but keep the same API. This will be used so we don't have to copy/paste src/ansi.py to src/imc2/ansi.py and duplicate stuff.
