Subject: [PATCH] build: point at testnet4-aware bitcoinj / bitcoinj-thin
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bump bitcoinj-core to 0.15.6-rsk-6 and bitcoinj-thin to 0.14.4-rsk-19 so the
federator's SPV wallet and the embedded bridge understand Bitcoin testnet4.
powpeg needs no code change for testnet4 — the federation is already built as
segwit P2SH-P2WSH-ERP.
