This is a big change that also many general fixes to problems found when creating transactions. In particular the Utxo and Tx formats and serialization functions were updated with additional information that would be necessary for rolling back old utxo and tx data data after btcd chain switches. This change also implements the json methods 'sendfrom' and 'sendmany' to create a new transaction based on a frontend request. Transactions are currently not sent to btcd since the tx relay code is not finished yet, so a temporary error is returned back to frontends who try to send new transactions.
