Probably a good idea.  You don't want to have to register a listener with
each GamePiece, though, so listeners will want to register themselves with
the Map.  However, you also probably don't want to fire one event for each
GamePiece that changes as the result of a user action (e.g.
GlobalKeyCommand).  You'll want to combine all those
GamePiecePositionChanged events into a single event to fire.  Could be a
little tricky.  A similar pattern is used in the Translate trait, where
multiple piece movements are combined into a single Command.
