- Resurrected refed commit that was adding tests for versioning API,
this time it's using dynamic replacements to match dynamic content of
the email using matchHTMLSnapshot / matchPlaintextSnapshot with dynamic
content replacements.

- we've deemed it useful to start to return `Content-Version` for all
API requests, because it becomes useful to know which version of Ghost
a response has come from in logs
- this should also help us detect Admin<->Ghost API mismatches, which
was the cause of a bug recently (ref'd issue)

- this commit turns the Ghost repo into a monorepo so we can bring our
internal packages back in, which makes life easier when working on
Ghost
