Subject: [PATCH] Add an app event for when a topic is fully loaded

If we are interested in page events (say analytics), they are reported
when the route changes, which does not wait for any promises in
`setupController` to finish.

A plugin might want to know when a topic has fully loaded, so this event
is triggered when that happens.
