The non-themed import basically is just a proxy using some
auto-detection to find out which theme to use.
As the app only uses the basic theme, this is what we'll import.
We already allowed individual wallets to get PIN-to-Open/PIN-to-Pay
but that is too advanced for most users. Not to mention that encrypted
private keys means a slower payment process and certain types of
features become impossible. Like auto-invoicing (incasso).
The gap, for mobile, is a simple not-encrypting password on startup
of the app which is likely what 80% of the privacy / security minded
people on mibile will be more than happy with.
This adds this mode and additionally streamlines the encrypted modes
of wallets.
