Apparently the change using BASH_VERSION never made it to get uploaded? Well, here is the change 'again'. Sorry!

Rewind rolls your local idea of the chain back a few blocks and tries to resynchronize. This can be good if you think you are stuck.

bytes32 would have worked if we sent a binary string, but uint256 seems much more friendly. We also now accept an array of uint256s for put'ing.
