moved portal::mapping api and data model from new-portal into the core, i.e.into acs-tcl and acs-kernel. renamed it from portal::mapping tosite_node_object_map, since that is what it is. enjoy.
Fixed SDM #1540: The 'bboard_message_set.message_set_content' querywas using '$content' instead of :content syntax, causing the value tonot be properly quoted, so it fails if you enter a single quote.
