Bitcoind outdated in main dockerfile

The Dockerfile is outdated and running an old version of bitcoind Bitcoin Core RPC client version v0.13.2.0-g0d71914.

Yeah, definitely a good idea to update. Though there is a problem using p2sh addresses (which are now default) with cert-issuer. So if we do update Dockerfile before testing out https://github.com/blockchain-certificates/cert-issuer/pull/84/files more then we'd need to atleast update the docs to specify that legacy addresses need to be created.

Might be a good idea to mention it anyways for Dockerfile.web since p2sh addresses are being created but having issues as specified here: https://community.blockcerts.org/t/unable-to-sign-transaction-testnet/1779/11

Agree the docs would need to be updated to continue using the legacy addresses. Also, we could script the address creating is i've done in this PR
