Bukkit

• Colors added to event messages to easily distinguish them from regular messages (customization coming soon)
• When !players is used, it sends a message to Minecraft
• Kicks are sent to Minecraft

Added by TerrorBite:

• Server messages (from /say in console) now shown in IRC
• When a player dies, the in-game announcement is repeated in IRC
• Message is sent to IRC when a player is kicked from the server, including the kick
