Hexadecimal display for color ID.

[GoogleCodeExporter]

RGB components : This is the primary need. Web workers manipulate #rrggbb a 
lot, and even I remember some #rgb from my Amiga time. I propose a specific 
setting that causes all display of R G B values to be in hexa (2 digits) 
instead of decimal (3 digits). The setting would be present in Settings screen, 
and saved in .ini. This affects the palette screen of course, but also the 
status bar display in some cases, such as when you hover the menu's palette and 
the status bar shows color number + RGB value.
About +/- value in palette (when you select a range): I guess it's more 
consistent to stay in hexa as well.

HSL components : In HSL mode, I am not sure the hexa scale is as useful. So I 
propose HSL stays displayed in decimal, always.

Color number : Some people may want the color numbers to be in hexa too. This 
affects many places, I think, and a single setting should control it (I meant, 
it's unrelated to the setting for RGB)

Comments, opinions etc. are welcome, as always. At the moment I think the RGB 
thing is the most useful.
