CHAT_PROPER version 5, by Kuntz

Created using Bukkit 1.2.5-R1.0 (Build #1438)
Tested on CraftBukkit 1.2.5-R1.0 (Build #2149) (April 16, 2012) using Windows Java 6 update 31

Overview:

A simple and one-of-a-kind chat mod for CraftBukkit. This should be fully compatible with other chat mods!

Implements 50 numerical chat channels. Players are only in 1 channel at a time.
Chat in channel 1 is broadcast to channels 2 through 19.
Players in channels 2 through 19 can send external messages to channel 1.
Players in channels 20-50 will only see messages from other playes in the same channel.
No config or setup needed!
Customizable chat format.

Commands:

/join # - Joins the specified channel #
/part - Parts the channel. Player will no longer receive channel messages
/c1 - Sends an external message from the Player to channel 1

Purpose:

To create a channel system that does not segregate the community. Named channel systems and private channel systems tend to break up the community into small groups and harm gameplay. I also wanted to allow players to read and participate in the main chat channel (channel 1) while having an easy way to chat with one or more other players in a different channel (2-19). And finally, players who do not want to be bothered by the main chat channel can join a channel (20-50) and be alone to chat with their friends.
