The scope being handed to (and retained on) the action
service was being used for two purposes:
1. handing data down to the underlying wizard steps, and
2. receiving data back from the underlying wizard steps.
This patch provides a mechanism for passing data down through
injection, and removes the need for event-based data return
by explicitly passing the captured wizard data to the submit()
resolution.
It also adds the controller scope to the allowed() and
perform() action service handlers to grant access to
contextual information without needing to attach state
to the service.
