Fixing Heroku deployment

Hi Jeff,
I fixed heroku deployment and described the issues in a Facebook message.

You'll be able to merge this code here with your repository right on github. If there are merge conflicts and you can't figure out how to fix them (they can be tricky), you can always just clone my copy of this code and start fresh (although in general this is bad practice).
