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.
Much better service.sh script. Uses nmap to determine valid hosts (big performance improvement). Added deploy and stop commands for service.sh
Fix for previous commit - there was a random line in service.sh
Update related to slave registration / pings

Updated Pinging Slaves. Modified SQL file to include Down servers which may be connected later (they are ping'd periodically.) Fix related to self-assignment in ServerHandler constructor
