UI support for hardware wallets (#4539) * Add parity_hardwareAccountsInfo * Ledger Promise interface wrapper * Initial hardwarestore * Move ~/views/historyStore to ~/mobx * split scanLedger * test createEntry * Also scan via parity_hardwareAccountsInfo * Explanation for scanning options * react-intl-inify tooltips * add hwstore * Listen for hw walet updates * Return arrays from scanning * Readability * add u2f-api polyfill * check response.errorCode * Support hardware types in state.personal * Tooltips (to be split into sep. PR) * Tooltips support intl strings * FormattedMessage for strings to Tooltip * Fix TabBar tooltip display * signLedger * Use wallets as an object map * PendingForm -> FormattedMessage * Pending form doesn't render password for hardware * Groundwork for JS API signing * Show hardware accounts in list * Cleanup rendering conditions * Update RequestPending rendering tests (verification) * Tests for extended signer middleware * sign properly & handle response, error * Align outputs between Parity & Ledger u2f * Ledger returns checksummed addresses * Update ethereum-tx for EIP155 support * Update construction of tx * Updates after sanity checks (thanks @tomusdrw) * Allow display for disabled IdentityIcon * Disabled accounts * Disabled auto-disabling * Password button ebaled for hardware * Don't display password hint for hardware * Disable non-applicable options when not connected * Fix failing test * Confirmation via ledger (u2f) * Confirm on device message * Cleanups & support checks * Mark u2f as unsupported (until https) * rewording * Pass account & disabled flags * Render attach device message * Use isConnected for checking availability * Show hardware accounts in defaults list * Pass signerstore * Update u2f to correct version * remove debug u2f lib * Update test (prop name change) * Add ETC path (future work) * new Buffer -> Buffer.from (thanks @derhuerst)
