IRC Bot disconnects with EOF unless it joins its own channel

tmi does not entirely adhere to the IRC standard, and as far as I know do not handle incoming PING’s. Only PONG [server] as a response to PING.

It replies to PING with PONG :tmi.twitch.tv and PING :something with :tmi.twitch.tv PONG tmi.twitch.tv :something. It’s how I measure my connection latency to the chat servers, and not replying to them would break compatibility with some clients.
