Biometría genérica (Face ID / Touch ID / Optic ID) y What's New 1.7.0

- AppLockService.biometryKind lee LAContext.biometryType; textos e icono del
  bloqueo y de la privacidad de saldos ya no asumen Face ID (Duo puede llevar
  Touch ID). Nuevas claves biometric_* en los 7 idiomas.
- Entrada 1.7.0 en el catálogo What's New (Duo, inspector, biometría) con
  strings en los 7 idiomas.
