- amount is the amount of the bet
- storage is true if using meat from Hagnk's storage or false to use meat from inventory
Place a bet of the specified amount using meat from inventory if storage is false or from Hagnk's storage if it is true. Returns the bet ID # if successful, or 0 if unsuccessful. You will be unsuccessful if you already have 5 bets out or don't have enough meat; or, presumably, if you don't have a casino pass.
