Title: Advertise device's capabilities via DNSSD TXT record

To aid in the device discovery process once the app is running, advertise some
information about the current device, including its name, model, iOS version and UUID (if available) via DNSSD's TXT record. It also advertises information about the app running and the version of that app.

This is critical to picking the right device from potentially many once the app has been launched.
