Do not put this on a server, it is not ready.

Implements a subset of irc in the style of https://github.com/sstephenson/hector. Like hector the supported commands are:

• USER and PASS -- Authenticates you to the server. (Your client sends these as soon as it connects.)
• NICK -- Sets your nickname.
• JOIN -- Joins a channel.
• PRIVMSG and NOTICE -- Sends a message to another nickname or channel.
• TOPIC -- Changes or returns the topic of a channel.
• NAMES -- Shows a list of which nicknames are on a channel.
• WHO -- Like NAMES, but returns more information. (Your client probably sends this when it joins a channel.)
• WHOIS -- Shows information about a nickname, including how long it has been connected.
• PART -- Leaves a channel.
• AWAY -- Marks or unmarks you as being away.
• INVITE -- Invites another user to a channel.
• PING -- (Your client uses this command to measure the speed of its connection to the server.)
• QUIT -- Disconnects from the server.
