* [NOD-201] Implemented the AddSubnetwork CLI tool. * [NOD-201] Fixed various bugs in AddSubnetwork. * [NOD-201] Fixed mempool maybeAcceptTransaction verifying gasLimit for a subnetwork registry transaction. * [NOD-201] Fixed serialization/deserialization bugs in addrIndex. * [NOD-201] Fixed BlockConfirmationsByHash not handling the zeroHash. * [NOD-201] Used btclog instead of go log. * [NOD-201] Made gasLimit a command-line flag. Made waitForSubnetworkToBecomeAccepted only return an error. * [NOD-201] Filtered out mempool transactions. * [NOD-201] Fixed embarrassing typos. * [NOD-201] Added subnetwork registry tx fee + appropriate cli flag. * [NOD-201] Skipped TXOs that can't pay for registration.
