+ and - button in the palette don't do anything in HSL mode

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open the palette window
2. Select HSL mode
3. Try to use the buttons + and - above and below the color preview: they 
don't do anything !

In RGB, these buttons modify the 3 sliders at once, making the color 
brighter/darker. I'm not sure :
a) This is an useful feature : we can do the same thing easily in HSL 
mode, which is only one click away
b) If we keep these buttons in RGB, what should they do in HSL ? Moving 
the 3 sliders sounds like it would give strange results...

Maybe we should simply hide or disable these buttons in HSL mode ?

I didn't see anything useful to do with these buttons in HSL, so I silently 
disabled
them. The cleanest would be to actually disable the buttons : greyed-out, no 
response
to click.
It is not so easy, because the buttons system does not handle active/inactive 
currently.
