Pick a title & scope for the book

"Decentralized Web Primer" is something I was working on before I became involved specifially with IFPS.

I do like the idea of using this as an opportunity to teach all of the core concepts of the decentralized (or really distributed) web, but that reaches beyond providing a complete set of tutorials for understanding and working with IPFS. We should decide up front what we're committing to.
