Unknown Quality in Profiles

This will let some anime that doesn't have a quality marker in the title be grabbed automatically. https://trello.com/c/rdxwJsLg/393-ability-to-add-unknown-quality-to-profile

Not a huge fan of the migration, but it doesn't need to be checked on every start either.

Also pulled some old code for re-ordering quality definitions.
The JSON? How do we want to deal with it? I get that it could change, but we're using these methods already when we talk to the DB already. I'd like to keep the JSON we save consistent, should we duplicate the settings we use?
