LOUDBOT FOR SLACK.COM CHAT
I STOLE ISAACS'S LOUDBOT AND TURNED IT INTO THIS. AT LEAST I DIDN'T USE PROMISES.
RUN THIS SOMEWHERE & POINT YOUR SLACK.COM WEBHOOK TO http://YOUR_HOST.COM:PORT/MESSAGE.
YOU WILL NEED TO DEPLOY THIS IN A DIRECTORY WHERE IT HAS WRITE PERMISSIONS BECAUSE IT WANTS TO LEARN FROM YOUR SHOUTING.
