Include console output in GUI

[DavidLeoni]

Currently in s-match GUI the user can't directly see the messages logged by s-match, he can only check them in terminal if s-match is launched from there.

It would be nice to add add the bottom of the GUI a little panel reporting terminal messages. These can be particularly helpful for components like Diversicon that may perform possibly long operations such as remote connections or even fetching databases.

I recall I've done this in the past in some project via a special logger which logged messages into a text box and even scrolled it to keep up with the latest messages. I'll have to look it up.

To start, check out SMatchGUILog4Appender.java (here in s-match-utils) and log4j-gui.properties (in older versions at SF).
