As is, the sidechain manipulation script chokes during the "send-to-sidechain" step. I've added rudimentary support for unlocking wallets. There are a couple of notes.

- As written, the user must manually edit the password. I'd prefer to make the password an optional CL parameter. If this is preferential, let me know and I'll go back and edit all files as necessary.
- While it's doubtful that the script will encounter a pre-0.9 BC Core, the code compensates for the pre-0.9 "wallet already unlocked" error (RPC_WALLET_ALREADY_UNLOCKED) if it's encountered. Any other error kills the script. It's a bit crude but it should work.

Thanks.
