SCRAM-SHA-1(-PLUS) + SCRAM-SHA-256(-PLUS) + SCRAM-SHA-512(-PLUS) supports

[Neustradamus]

"When using the SASL SCRAM mechanism, the SCRAM-SHA-256-PLUS variant SHOULD be preferred over the SCRAM-SHA-256 variant, and SHA-256 variants [RFC7677] SHOULD be preferred over SHA-1 variants [RFC5802]".

Can you add support for?

Would gladly merge a pull request

XMPP servers remove the old history unsecured MD5 support, any news on it?

[GitHubbie0836]

In Miranda NG, they implemented SCRAM-SHA-1-PLUS support - maybe this will help you somehow!
