wallet: auto sync outputs and key images in cold signing files
When passing around unsigned and signed transactions, outputs and key images are passed along (outputs are passed along unsigned transactions from the hot wallet to the cold wallet, key images are passed along with signed transations from the cold wallet to the hot wallet), to allow more user friendly syncing between hot and cold wallets.
