Stub of pinging slaves and shadows by master (not run now). Modified DFSProperties: one port 9090, new variables like 'replicationFactor' 'debug' 'pingEvery'. Debug for ls - if 'debug' is true, it will show every server's content, not only list of files in whole system. Fixed client connecting wrong IP on start. Fixed some EmptyRepository exception issues (using coreStatus instead). Added nice logging for service.sh - logs from all servers are placed in 'servicedebug' file. Cleaned up service.sh output.
