c957107d85 Fixed the same stupid bug about endless looping on palette reduction again.

6cdc5e3042 -Use nearest neighbour and no error diffusion when loading 24bit images 
-Some cleanup to the palette computing function, but no real improvement. I can't get it to perform better ...

4e0d95b5e7 New: PNG 24bit loader (issue 201). Fixed greyscale PNG loader which never worked. Fixed 24-bit image loading on program startup which didnt update palette.

e877292ca2 The cluster system for color reduction when loading a truecolor image now uses a linked list instead of a table. This fix a potential problem because there was an overlapping memcpy. It also avoids copying the big cluster table around and just moves pointer around. It should be faster but I did not really noticed any change on my computer :(. Maybe it's too fast... 
The same can probably be done for the gradient sets.

506ea20d36 Sparc CPU does not like accessing non-aligned things. Depack some structures so the program don't crash. We should probably fix every struct, but I'm too lazy to check all of them right now (could corrupt saving and/or loading). 
Added Gürkan Sengün to the bugfinders as he found the problem. Thanks !

428e1c36cf Some more optimizations to the color reduction algorithm. Now runs in a decent time on my laptop :) 
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 ?

7c658a6855 Some fixes to the floyd steinberg dithering. The error was added to the neughbour pixels, it is now substracted, the results are much better. However, the palette seems to lack saturated colors (in comparison to the one generated b ygimp, wich gives more dithering, but better overall subjective ressemblance to the 24bit image. Maybe having less dithering is fine for us, as we are in a pixelart painting program afterall...

14accb544b Palette now uses RGB components in the full 0-255 range instead of 0-63. 
All palette functions can be used in HSL color space too (multi-select, etc).
Fixed some more missing refreshes in Palette screen.

e31b88ceed Palette sorting works 
-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.

fc41bbe89d Implemented palette sorting. There are problems as we're sortig with HSL color system and the rgb2hl function doesn't return s... we'll have to add that as we can't say if we're looking at red or grey (both have H=0). 
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.
