only one timestamp per log line please
removed the add/remove peer commands, now we do it using regular RPC instead, controlled by the current master. merged clean and sync into one func. created ring.Peer#Call and #Go to simplify rpc calls. added ring.Peers#ContainsPos to simplify testing of peer list content. created ring.Ring#MarshalText and #UnmarshalText to make it json encode properly. renamed sync_test to node_test. made storage.DB#hash include the key in the hash, to avoid databases with just a single similar value under different keys having the same hash. added a logs string to storage.db#Sync to allow some debug logging.
