* replace path/push/pop mechanism as it doesn't work well at reporting where differences/validation errors occur. * add getParent() to DbObject - so that a path-style identifier can be deduced for a DbObject when needed * add DbProperty to specify a specific DbObject's property and value -- acts as a schema location pointer * refactored Result code (need difference result and validation error result) git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@31527 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
