811f614515b6fb1ae5689bf02ec830bdc7ff62ac fix(cbf): typo and cbf dir config when sqlite feature disabled (Steve Myers)
b04fed2e8a58dd6b4e001c64d03d85ad46cf7d3c feat(cbf): implement transaction broadcasting (rustaceanrob)

Pull request description:

  The actual implementation comes down to listening for an info message that reports the transaction was sent to a peer. For simplicity I am ignoring any wallet updates, but if the user calls the `Sync` command they can catch them. Follows up #181
