v0.8.4

Fixed

• agents: namespaces written by 0.8.2 keep their people after the upgrade.
  Namespaces now list people by e-mail address, but a record 0.8.2 wrote names
  its creator and members by user id — and those entries matched nobody, so
  everyone lost access to their namespaces, with no way to repair it in the
  UI. An entry without an @ is read as a user id again and matches the
  account that signs in with it. Likewise, mindconnect.namespace-admins set
  on an installation whose default namespace already had a record added
  nobody to it and locked everyone out; the named admins are now added to the
  existing record.

What's Changed

• Namespaces: records from 0.8.2 keep their members and admins after the upgrade by @beisdog in #165
