Connector::Multi now uses itself (not baseconnector) to resolv
links to connectors, which allows references inside connector
definitions (e.g. LDAP Password via KeyNanny)

The definition of get_meta method no longer includes optional return of
the value and does NOT NECESSARYLY test for exisitence of a node any longer.
If you used get_meta to test for existance, please check if the used
connectors support it.
