added cancel game scenario to game management
refactored game-management to game-canceling

trying to capture a true feature that can potentially change over time,
as new stories come into the backlog.  starting game seems to be an
implied feature and as of now does not justify a separate story or
feature set

playing).  future scenario could be to cancel a game that is paused, or
something like that
