[wishlist] make gtk laf default for icedtea-java

package hint: icedtea-java7

I second this request. Java apps with GTKLookAndFeel look much better integrated than the ones with MetalLookAndFeel.

I think all we need to do is ...
1. Add a /etc/java-6-openjdk/swing.properties file with following content.
# Swing properties
swing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel
2. Add a symlink to this file at /usr/lib/jvm/java-6-openjdk/jre/lib/

Please find attached screenshot of an application 'electric' with gtk look and feel.

Please find attached screenshot same application 'electric' with metal look and feel.

Hi,
Unfortunately the GTK+ LAF is NOT fully compatible with default Metal LAF,
and in some cases may cause major application problems (including crashes and data lost).
Even the new Nimbus LAF (included in Java 6 Update 10) is not set as default to preserve backward compatibility.

However, there are two good solutions:

* User/Package Maintainer can modify particular application shortcut to add
"-Dswing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel" parameter.
Example command:
java -Dswing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel -jar application.jar

* Java Developers can set Look And Feel to:
UIManager.getSystemLookAndFeelClassName()
The getSystemLookAndFeelClassName() method
automatically returns
"com.sun.java.swing.plaf.gtk.GTKLookAndFeel" (GTK+ LAF) on Linux/GNOME platform.

On Intrepid, the following is true:

But Java applications don't use the Swing GTK look and feel by default.

the new properties file is added. with the default commented out. now people can change it on their own. I intend to keep the nimbus l&f for lucid.
