Fix issue 185 (XOR highlight) :

Browse Source 
* Use a simple optimization algorithm to compute a good set of XOR color pairs
 * Algorothm is not very optimized (complexity is up to n^3). In practize, it stabilizes after 2 to 3 rounds of swapping colors
 * Use this color table for all XOR effects
 * Setting for grid color is now removed
