Sprite Palettes

I found the palette offset information for the sprites so now the color palettes seem to be correct.
A few impressions:

 I also rewrited the loading algorithm for the sprites and it is much faster now. I needed this improvement for the display of the sprites on the maps which will be my next goal.
And as a little outlook:
I need to finish the map data compression routine to write the edited map data back to the ROM. Once this is done I will release the next version of the editor that will enable map editing and mabye even sprite editing.
