<Swing Dev> Minor enhancement for JColorChooser

[Jing LV]

Hello,

I find some minor problem on JColorChooser, a few key items are missing
that may help the customers to understand. For an example, on the HSB
and RGB tabs, the spin fields do not have accessibleName strings. I
wonder if add them would help JDK and the customers.
If no object, I'd attach the small patch for this.
