Heroku-namespaced buildpacks in API and CLI

Change effective on 03 November 2015

Heroku’s support for explicitly configuring a buildpack now allows you to specify one of the officially released Heroku buildpacks as a value. For example, you can run this command with the Heroku Toolbelt to configure the Ruby buildpack:

$ heroku buildpacks:set heroku/ruby

This feature is available for the default Heroku buildpacks only. You may still use a URL for a custom buildpack. The convention is also supported in the Platform API.
