L&S - Poker chip tree art assets

[Cervator]

We need block shapes and textures to support the poker chip trees - concept art at http://forum.movingblocks.net/threads/light-and-shadow.762/#post-7537

I imagine the "crown" of these trees to be about 3x3x1 and in theory they could be octagonal with just a simple slope in each "corner" - but maybe we can do better than that :-)

Individual textured blocks would be fitted together by a custom tree generator

Moved out to the "extras" milestone after @skaldarnar tried the poker chip in-game and had it not turn out too pretty. Not high priority anyway, we got several other nice art assets making it in :-)
