dix: Praise clients which haven't run for a while, rather than idle clients
A client which is ready, but hasn't run for a while, should receive the same benefit as one which has simply been idle for a while. Use the smart_stop_tick to see how long it has been since a client has run instead of smart_check_tick, which got reset each time a client was ready, even if it didn't get to run.
