v3.6.0

Enhancement

• WebAuthn via NFC. However, this feature is marked as experimental by libfido2, which is used here. So there might be devices that do not work or other problems.
• WebAuthn token can be used for offline authentication if it is marked as such in privacyIDEA.
• Use of user_verification=discouraged policy in privacyIDEA is now considered. In offline scenarios, the PIN prompt can be controlled via webauthn_offline_no_pin registry setting.
• Changed translation system to allow adding or changing translations without the need to install a new version. Also added spanish translation. Both contributed by charlyR (#158)

Fixes

• Fixed a bug that would cause otp_link_text to be ignored.
• Fixed a bug that would cause the (customizable) OTP failure text to not be displayed.
