2. Added G0RDI's 'links' command.
3. added update_sysop.pl which cleans out all previous versions of the sysops
information from the user database and recreates it with that in DXVars.pm
+4. Added node type to links and who
+5. Hardened up the cluster->client link in the cluster software so that
+rubbish on port 27754 doesn't (usually) crash the cluster.
