Added rum price to TransactionStartEvent.  GameLogic fills this in when it makes the TransactionStartEvent.  Still need to get the game view to use this data instead of calculating it on its own.
Human game view now uses the rum price supplied in the transaction start event to display in the transaction window, rather than its own calculation.  Tested briefly, looks to be working.
