Sort out the naming of the various parts of an identity.

* A `cookie::Identity` (`IdentityCookie`) is a specialized CookieJar for working with identities.
* An `Identity` is a token/login pair.

I hope for this to be a bit more legible.

In service of this, `Login` is no longer extractable. You have to get an identity.
