[Rxtx] gui v1.0

[Dr. Douglas Lyon]

Hi All,
Here is my first attempt at GUI for serial ports:
http://show.docjava.com:8086/book/cgij/code/jnlp/gui.run.RunSerialPortPanel.jnlp

The features:
1. It works on PPC Mac, x86Linux and WinDOZE.
2. It persists the settings from one run to the next in user preferences.
3. It only configures one serial port (if you need to communicate with many
serial ports at the same time, this is not for you).
4. It uses Swing
5. It can probably work on other platforms, I just don't have
the native methods for the jar files linked into the web start application,
yet.
6. It is simple looking.

Please let me know what you think of it.

Thanks!
