commit 8906c31dd68f9836e4bc27dbd356d842d009c4fb

    with transproxy allow localport access for proxies
    
    when transproxy all is on, or when app by app proxying is on,
    access to the localhost transproxy, SOCKS, HTTP, tor DNS and
    other localhost ports should be allowed for apps that want
    to speak directly to tor regardless of transproxy being enabled
