Title: Updates README to include reference to HUBOT_IRC_PRIVATE env variable

Had to look through the code for this one, so I figured there could be a hint. Based on my reading, this variable being set to `true` prevents:

* Hubot from responding to PRIVMSG commands
* Hubot from accepting `/invite #channel` commands automatically
