Title: Login should ignore converter passwords by default

By default we shouldn't try to convert non-compatible passwords. Conversions should enable this option automatically to allow proper conversion of passwords. There is no reason to attempt to fix these passwords for SMF installs that are not conversions and is just a waste of resources to do so.
But we always try to fix old SMF passwords, as there is no reliable way to determine if those options need to be enabled to fix previous bugs, without doing the password checks in the first place. I suppose we could make this a drop down to also disable SMF ones, but seems worthless.
