Pong Node v2.60

Adds checks to ensure balance matches new transactions so that the user can be notified if that occurs and given a clue about how to remedy the unlikely situation. This update also changes the method for checking for response confirmation and uses the daemon to check if there are any responses that fail to show up before initiating a retry. Smart contract ownership transfers appear to work as desired and the token amounts should display correct denominations (token or dero).
