Use manifest defaults when adding components and refresh properties from device

- Populate prop elements with manifest default values when adding
  components in both offline and live mode
- Send config values from manifest in SOX add command for live devices
- Refresh button in properties panel now fetches fresh values from
  the connected device before re-reading the DOM
- Properties panel fetches device values on open in live mode
