Since Net::NNTP doesn't support Socket or RawSocket options/accessors like Mail::IMAPClient does; we must perform localized @ISA manipulation and massage Net::NNTP into using IO::Socket::Socks rather than IO::Socket::IP. This is a bit fragile, but Net::Cmd and Net::NNTP rarely change; and I keep an eye on them, anyways.
