Avatars are purposely accessible without authentication
(5e3b5b6d7c) because they can be in public
collections. Trying to restrict this by checking whether they're in fact
present in some public collection is rather expensive, so let's keep
them public.
The new integration test shows the desired user-facing behavior, which
is to make it easy to login without a tenanted URL and to jump between
tenants.
Note that we track two things in the identity_token cookie: a signed
id, and the updated_at for the underlying Identity object. This allows
us to effectively cache on the Identity without having to hit the
database, by using an Identity::Mock object that is compatible with
etag and cache methods.
- New untenanted Identity and Membership models
- New `identity_token` cookie with path "/" holds state across tenants
We're not sure whether the untenanted database will be sqlite or
MySQL, and so I've been careful to minimize
- database reads, placing them behind etags and caching
- database writes, only writing when a new Session is created (login)

- the untenanted "login_help" page shows all linked memberships
- the jump menu shows all linked memberships (except the current)
Also introduced a utility script to populate existing employee
Identities, grouping accounts by email address.
