skitter is a repl friendly event system for games.
All listeners now have 3 manadatory args before the slot key args. (event timestamp tpref)
tpref (third party reference) is either nil or whatever argument the user passed to #'cepl:step-host
This assumes that the host passed it on to skitter. Currently I expect Im the only one using this so I can say it does :p
I have updated cepl.skitter to use this field
