• Split connection system from Bot.php into Socket.php
• Split various static functions into FunctionCollection
• The bot now waits for NickServ authentication before joining channels
• NickServ is no longer hardcoded
• Command prefix moved out of main() into __construct
• __construct now actually does something (removed all setters from phpbot404.php
• Merge PR #4
• Split listener system from Bot.php into a Listener/Manager class
• With that, remove the listener detection code from Bot.php and put it into Listener/Manager class; hook it into the main loop
