    [Setup] Allow (major) upgrades, deny downgrades (fixes bug #602172)
    
    Added standard by-the-book major upgrades. Newer versions of Tomboy
    now silently replace the previous version. This works right away and
    upgrades all previous builds, starting at 0.13.0.
    Future build based on this change make sure that they don't downgrade
    the already installed version (if that is intended, the user has to
    manually uninstall the newer version first).
