When a wallet is opened, a rescan request will be sent to btcd with all active addresses from the wallet, to rescan from the last synced block (now saved to the wallet file) and the current best block. As multi-account support is further explored, rescan requests should be batched together to send a single request for all addresses from all wallets. This change introduces several changes to the wallet, tx, and utxo files. Wallet files are still compatible, however, a rescan will try to start at the genesis block since no correct "last synced to" or "created at block X" was saved. The tx and utxo files, however, are not compatible and should be deleted (or an error will occur on read). If any errors occur opening the utxo file, a rescan will start beginning at the creation block saved in the wallet.
