All Simulators: Horizontal scrolling does not work with Java 7

[markarmb]

For example, run projects/05/CPU.tst and try to scroll output to see right-most columns. (This worked OK with Java 6.)

There is a proposed fix in this n2t forum post

I had an issue where I could not scroll horizontally within some of my subwindows (e.g.: HardwareSimulatorMain's HDL window). To fix this I added this line to the WideTable constructor.

HackGUIPackageSource/HackGUI/WideTable.java

    public WideTable(TableModel model, int width) {
        super(model);
        this.setAutoResizeMode(JTable.AUTO_RESIZE_OFF); // <-- Added to scroll
        this.width = width;
    }
