    main-window: Don't mark PACKAGE_VERSION as translatable
    
    It doesn't get extracted as a translatable string because xgettext
    looks for string literals in the un-preprocessed code. Even if it did
    work, it keeps changing for every release, and it would be difficult
    to respect the string freeze.
