Add: Loop in NNTP decompression to wait for the server to return data on possible terminator (should help with "msgs is not array").
Chg: Use stream_socket_shutdown instead of fclose when closing the stream socket client on NNTP (faster).
Chg: Don't use feof on _isConnected in NNTP for certain uses (feof can return false even if the socket is still open).
