Hi Marcel,

Okay, but #userAndPasswordFromSettingsDo: exists and works now.  There's an
opportunity to improve the system by mere deletion.

Except we're not wiping the contents on image save, so everyone's passwords
are being left in dozens of images.  People reuse sensitive passwords.  We
should care about that.

For this, please prioritize for security first.  Monticello doesn't run
without the filesystem.  We have an easy opportunity to better
safeguard private user data, is there something else that's rubbing you
wrong about this idea?
