Renamed to eth-sender. Can still sign eth-txs at multiple gas prices, fan transactions to multiple nodes, wait for confirmation between transaction batches (now of user-specified size). The previous nonce reading implementation was broken beyond belief and has been taken out. Can be reimplemented once RLP decoding is in the stdlib.
