        - corrected minor spelling fixes thanks to an rt patch.
        - fixed AnyEvent::IRC::Connection::is_connected to actually return true
          when connected.
        - AE::IRC::Client::connect can now also connect only with a timeout without
          having to register.
        - Server reply of 001 is now also considered as "successfully registered".
          Thanks for Lee to spot this.
        - "quit" event gets the right parameter from the message now. Thanks to Lee!
