Code "cleanup": Functions that create a button now return its address.
This helps reduce the number of files that use the globals "Fenetre_Liste_boutons_*"

There may be some more small optimisations possible in this area... i'm still thinking we could get a better palette by putting more priority on highly saturated clusters, but, as we don't store the saturation property in the clusters, it seems difficult to do. Probably it would require switching to HSL before doing the clustering, and finetune the multiplications done in Cluster_Split. Note: these modifications (and the one in the previous commit) will probably crash badly if using the reduction algorithm with a smaller precision than 24bpp. The program will try to do that if it is unable to malloc the big lookup tables (we need a table of 256^3 = 16Mbytes for the color lookup, and when loading we also have the 24b image in memory, and also the clustermap, and the occurence table, wich is 256^3*4=64Mbytes). So, either we assume every computer out there has 128Mb RAM, or I'll have to change my code back to use a lower precision if the malloc ever fails. Anyways, who's wanting to open files bigger than our marbles.pcx in grafx2 ? and who except me is running a computer without swap memory at all ?

All palette functions can be used in HSL color space too (multi-select, etc).
Fixed some more missing refreshes in Palette screen.

-still slow
-seems there is a bug in the HSL calculation for green and blue, they get sorted incorrectly
-maybe the new S parameter should be used in clustersets, because now we are not differenciating grey from red !! maybe it's done elsewhere, we'll have to check.

Also, there is a problem with the makefile under linux. The .dep is set for checking the .o in the win32 folder. It still works but recompiles everything at each change.
Also added a button to enable HSL color editing in the palette screen. We'll need a hls2rgb function, and some other tweaks and reworks to the palette screen.
