CRM-14169 - Reverted the change to require access CiviCRM since creating an event does work for auth user with access CiviEvent and there are use cases for this. We will add a config warning separately if inappropriate perms have been granted to anonymous users. Removed access CiviCRM requirement from ajax.locBlock since that breaks the Location tab in events for users who can otherwise properly create an event.
