CMS-4072 : Add photographer and copyright to the ImageContentDataInput class - Implemented, with minor changes to xml-creation.  Also fixed bug that ignores change comment.
CMS-4071 : Add site-key to the create and update content commands in the API to make event log entry correct - Implemented and tested with plugins
CMS-4054 : Register auto-logins in the event log - Precommit of bug discovered during development: A QualifiedUserName will never have both userstorekey and userstorename, so the createUserStoreDataDoc will either create an empty element or an element with an empty name.  Improved now, to include either key or name in XML.
