Improve JavaDoc readability:
- Use plain English "or" instead of "|". Thanks to operhiem1!
Fix misleading logging:
- Don't log "New identity:" in constructor which we use in Identity.clone(). Clone is being used very often by event-notifications when an identity changes, it doesn't indicate that a new identity was created.
- Instead, add proper logging to the places which use the constructor and actually create an identity
- Also, tweak the loglevels while I'm at it.
