    lib: Add PARENTAL_NOT_LAUNCHABLE quirk to prevent launching apps
    
    As well as filtering installation of applications, parental controls
    need to prevent launching banned applications which are already
    installed on the system (perhaps for other users). While installation is
    controlled through OARS ratings, launching is controlled via a
    blacklist.
    
    Add a new quirk to GsApp for apps which should not be launchable due to
    violating the blacklist, and check for it on the details page.
    
    It is up to vendor plugins to implement the policy to set this quirk on
    apps.
