Enable different distributions of CBP

[aweiteka]

The CBP content should be packaged for different audiences. For example, the Fedora upstream community would like a set of content customized for their needs. Add asciibinder support to enable tagging of different content.

This involves reorganizing some content into logical files so topics are easily managed. It also involves enabling Asciibinder for the project and updating documentation for how to contribute to the guide.
