a POE irc bot

Here's the source for the POE irc bot that I gave on the Dutch Perl Workshop. It consists of a bot that evolves in steps, each new step adding new stuff.

• bot1, does absolutely nothing except print debug info to the console, and connecting to IRC.
• bot2, is an extension of bot1, adding hooks in channel messages and private messages, and doing DNS lookups.
• bot3, is an extension to bot2. Not only offers this DNS-lookups from IRC, it adds the reverse: DNS lookups via IRC. It listens on port 53/udp for queries, and will ask the IRC channel any question it receives, sending the answer back to the DNS system.
