Updated colors of tile items 178-185 to match map colors. More...

178 Gems has the aforementioned issue of sub-items having different colors. For now it is left the default.

179 - 183 have been provisionally named Moss <color> and have been set to Stone="true" and Special="Grass" to properly blend.

184 has been named Moss Plants and needs UV coords mapped out in the future. As well, the different UV coords have different map colors on their respectively colored mosses. For now I've given it the same gray as 165 Deco Large so as to "match" all the moss colors.

185 Deco Small has a plethora of colors for the various sub-items, I went with the bone related color and increased the brightness 12.5% to differentiate it better from 1 Stone.
