activate_user should send the user_activated signal

[w00kie]

Shouldn't the registration.models.RegistrationManager.activate_user send the user_activated signal? It would sure be helpful when writing my own unit tests...

Another think you might want to do is trigger a push to a contact management system (mailchimp, sendgrid or stripe for example) when a user is activated through the admin approval backend.

The signal is sent in the ActivationView, see https://django-registration-redux.readthedocs.io/en/latest/signals.html
