Fixed EH17-Hase.ino: No longer shows adjacent Green patches.

There were two uses of Green in table Colors. The effect was that even though no two neighbors used the same color index, there were neighbors that both used Green -- with different color indices, but the same RGB values, resulting in adjacent green patches.

Another effect should be that Orange is now used as well. It was never used because the extra Green pushed the trailing Orange out of range [0-7].

Also wrapped Colors to one color per line.
