Two factor authentication plugin using YubiKey

With this plugin you can use a YubiKey hardware token device (available from Yubico.com) for two-factor authentication in Joomla!. The OTP validation is performed against the YubiCloud servers.

Improved YubiKey handling

- Error message shown when you try to activate this feature but the OTP is invalid or doesn't validate against YubiCloud's servers
- Shuffle the list of YubiCloud servers, using a different, random one every time (helps spread out the load and improve the resilience of the implementation)
- Use a time based nonce instead of the form token to prevent YubiCloud responding with REPLAYED_OTP if the form token doesn't change between subsequent attempts
The YubiKey authentication would always return false
