- added new aspect called "cm:author" with a single text property "cm:author"
- fixed the content meta-data extractors to set the new cm:author property rather than the system cm:creator property (which was causing a couple of bugs spotted recently)
- fixed the web-client to set the new cm:author property rather than the cm:creator property from user entered data into the UI
- fixed web-client config of document properties screen to display cm:author
- fixed client to not allow editing of the cm:creator value
