    app: rename "last-run-version" property by simpler "config-version".
    
    Thinking again, this is simply the version of the config files, mapping
    to the application version. Even though it's not really a user-visible
    string (except in config files themselves), I find this a much more
    elegant name than the ugly "last-run-version" (which is not even true
    anymore once startup passed; it's only the last-run version info at very
    beginning of the startup process).
