Fixed a bug that caused sessions to get overwritten and some of them would seem to freeze, the whole thing relied on undefined behavior. This bug was a static variable that copied sessions all around globally. Rewrote the config to support a few more options (the PasswordType is coming soon) and explained how the new authorized_users files work. Public key authentication now has the same number of retires that password authentication has (this aligns with how OpenSSH does it) and the number of retries can now be configured in the configuration.
