This conversion, from an iterator of type-specific events (say, `user::Event` or `message::Event`), into a `Vec<event::Event>`, is prevasive, and it needs to be done each time. Having Broadcaster expose a support method for this cuts down on the repetition, at the cost of a slightly alarming amount of type-system nonsense in `broadcast_from`.
Historical footnote: the internal message structure is a Vec and not an individual message so that bulk operations, like expiring channels and messages, won't disconnect everyone if they happen to dispatch more than sixteen messages (current queue depth limit) at once. We trade allocation and memory pressure for keeping the connections alive. _Most_ event publishing is an iterator of one item, so the Vec allocation is redundant.

The taxonomy is now as follows:
* A _login_ is someone's identity for the purposes of authenticating to the service. Logins are not synchronized, and in fact are not published anywhere in the current API. They have a login ID, a name and a password.
* A _user_ is someone's identity for the purpose of participating in conversations. Users _are_ synchronized, as before. They have a user ID, a name, and a creation instant for the purposes of synchronization.
In practice, a user exists for every login - in fact, users' names are stored in the login table and are joined in, rather than being stored redundantly in the user table. A login ID and its corresponding user ID are always equal, and the user and login ID types support conversion and comparison to facilitate their use in this context.
Tokens are now associated with logins, not users. The currently-acting identity is passed down into app types as a login, not a user, and then resolved to a user where appropriate within the app methods.
As a side effect, the `GET /api/boot` method now returns a `login` key instead of a `user` key. The structure of the nested value is unchanged.
