The auto login filter is wrapped with logic to disallow it's use with an Activation field in the Members section.

This logic should be removed, as the Activation field itself will determine whether a member can log in or not.

Suggestion: We promote auto login to use it's own logic instead of piggybacking on the Update Password Login filter. Reason being, that there is no result appended to the event messages when this filter fails, for example, if another filter prevents the rest from running. Unless I'm missing something and this is expected behaviour?
