We haven't sorted out how we're going to handle differing lifetimes of consumers
and mediators (with a delegate or a proxy or something else), but I think in the
meantime, where possible, we should just make consumers a required property of
mediators passed on construction. So in this case the mediator would be created
at the same time as the view controller, and have it passed into its init.

Sounds like a good idea. Done.
