Humongous merge. It is incomplete, however; faces-config-navigation.xml and ClientConfigElement
were both beyond me, and are just the raw conflict merge data. If Kev can't figure out how they should go together by tomorrow AM (for me) I'll dig back in. git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/BRANCHES/WCM-DEV2/root@4306 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
