The Android design is that you can "close" the app while it is not
actually killed. It stays frozen but in the background.
This makes Pay check the clock on 'wake up' and if 10 minutes has passed
it will lock again.
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.
