completed implementation of GetContentsTable, GetHierarchyTable, and OpenEntry
for folders and for the Logon Object. Also added a OTLKCON_ConfigureBackend
API function to add configuration information through ServiceEntry (this should
be moved to ConfigureGui or some similar function to be discussed.) Finally,
added STDMETHODIMP to the declaration of OTLKCON_ServiceEntry, and made minor
changes to load the backend during configuration.
