feat(Settings): Add system for versioning and upgrading Settings

Similar to how History handles SCHEMA_VERSION. Run separately on global and
personal settings, since some state in global, and personal settings can’t be
done globally since they require the passkey.

Restrict a user from downgrading past the saved settings version, due to
possible compatibility breaks or old qTox versions re-introducing corrupt state
that was already healed.
