Fired when the user enters a new zone or city. e.g. moving from Duskwood to Stranglethorn Vale or Durotar into Orgrimmar. In interface terms, this is anytime you get a new set of channels.
- When this event fires, the UI may still think you're in the zone you just left. Don't depend on GetRealZoneText and similar functions to report the new zone in reaction to ZONE_CHANGED_NEW_AREA. (untested for similar events)
