Updated AWS lib, and hash logging

I've updated the AWS lib to the newest version 1.3.33, but more importantly I've added the TreeHash of each uploaded item to the log output so that it can (if needed) be compared with the hashes included in a vault inventory -- while not vital it will make integrity checking easier.

This request is related to some debugging I've been doing where the AWS is reporting an error on upload so I've re-uploaded the archive only to find two copies in the vault at a later date. Keeping the hashes in the log should help ensure that I know for certain which copy (if any) in the vault are valid if this occurs.
