org.netbeans.modules.form.palette.CPComponentLarge$PaletteListRenderer

1.
crashes with NPE when ui default for "Button.border" is null. This can happen
using certain look&feels(including the one I am developing at the moment).

The following change would have no impact on the default look&feels, but would
work wonderful (instead of crashing) with several other look&feels:

 public PaletteListRenderer() {
    ...
    buttonBorder = button.getBorder();
    if (buttonBorder != null) {
      emptyBorder = new EmptyBorder(buttonBorder.getBorderInsets(button));
    } 
    ...


2.
If the look&feel defines a minimum width for buttons which exceeds the palette
icons, the left alignment looks awful.

Workaround: setting to center alignment

     public void setIconSize(int size) {
        if (size == BeanInfo.ICON_COLOR_16x16) {
/* --> */  button.setHorizontalAlignment(SwingConstants.CENTER); // changed this
           button.setVerticalTextPosition(SwingConstants.CENTER);
           button.setHorizontalTextPosition(SwingConstants.RIGHT);
        } else {
