Release notes for MindTerm 3.4.1

This version fixes a number of bugs which were present in 3.4 and adds
some minor enhancements.

* Enhances SSH2Transport to keep track of number of bytes sent and
  received. The counts can be received via the methods:
    public long getTxBytesCompressed();
    public long getTxBytesUncompressed();
    public long getRxBytesCompressed();
    public long getRxBytesUncompressed();

* Accept channel windows sizes larger than 2^31-1. There are SSH
  server implementation which announce such ridiculous channel window
  sizes so we have to accept them.

* Changed the class SSH2AuthKbdInterac (which implements keyboard-
  interactive) to look for a property with name "password" and use it
  as the password if found. The password is only tried once and any
  further questions from the server are sent to the interactor.

* Various improvements to the handing of X.509 certificates. The API's
  give more information about them and a bug with reading
  certificates from Netscape databases have been fixed.

 * SSH2SessionChannel did not use the correct default receive window
   and max packet size values.

* Filter out ^S and ^Q when printing output in terminal emulator. That
  is because some servers sends it every now and then.

* SSH2SFTP now allows max packets of up to 256Kbytes. But do not
  allocate that much space unless really needed.

* Do not disconnect the entire session if we get CHANNEL_EOF or
  CHANNEL_REQUEST after we have received a CHANNEL_CLOSE. The server
  should not send this, but let us be forgiving and just simply ignore
  it rather than giving up completely.
