Title: Included info on installing cloudant heroku addon in README

I think in order to add heroku addons you need to have a credit card on file (even if they are free addons).

`vulcan update`

fails silently if it is unable to add the cloudant addon and then will fail at the 'Uploading source' step in the process.
