vdu: allow {role:".."} in maintainers list

Treats any user with the specified role in their "roles" list to update
the package doc.

via a server admin, so the API for managing groups will probably need to
be outside of the Couch App itself.
entity-scoped modules

Syntax: `@entity/module-name`

This is just the bare minimum validate_doc_update function change that
is required to support scoped modules.

Even if they are in the maintainers list, users must *also* have the
entity set as a role in their user doc to make changes.
