Automatically populate the contacts widget via [YellWOWPages](yellow.wownero.com/). One may still add custom contacts - they will get saved normally like before.

Requires https://git.wownero.com/wowlet/wowlet-backend/pulls/17

Adds some new CLI arguments

- `backend-host`
- `backend-port`
- `backend-tls`

They refer to wowlet-backend
