Been a while: properly syncing /config/*.config with /config/*.Release.config
Update incorrect summary
Apparently we rely on <error404>1</error404> to be in umbracoSettings.config
Fixing some potential upgrade issues and two issues found with the legacy member API

- The RequiresUniqueEmail check was wrong, previously the assumption was: if there's no e-mail then don't check for uniqueness
