Vulnerability in node-combining function

Hi @olalonde,

I think there is a vulnerability in the node combining function, node.hash = sha256(string(node.sum) + ...)). I've posted a thread on it on BTCTalk here: https://bitcointalk.org/index.php?topic=814935.0 -- please let me know if it's not clear!
