Suggestion: Provide option for 'unpack' command that unpacks adventure documents into their subordinate component documents

[silvative]

While they're a single document in themselves, adventures are a bit of a special case and each one sort of functions as its own special compendium- it would be nice to have an option to get an individual file for each of the contained documents, rather than a single file for the entire adventure.
