- 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 git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@2034 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
