+1. change some print commands in DXMsg to dbg('err'...
+2. overloaded confess, croak et al into DXDebug and removed Carp from
+everywhere and checked that the necessary debugging really does go into
+the debug files now.
+3. changed print statements in cluster.pl to dbg('err',... so they go into
+the debug files as well.
