Subject: Added a CheckSumServer (handles template checksum , so there is no
 longer the need to connect to LL userserver). Currently onlt active in
 sandbox mode (someone simple needs to add "CheckSumServer checkserver = new
 CheckSumServer(12036, m_console);" to the grid userserver). Then when
 starting up the SL client add " -user localhost" (or whatever the IP address
 that the sim or grid userserver is at) to the command line
