Alchachess: Dev Log 17

Reduced board size and started changing the atmosphere to be a little darker. 

I made the board smaller to decrease the amount of things the player has to track. Having to keep track of the health, position and elements surrounding each of your pieces and your opponents pieces was a bit overwhelming with 8 pieces per side. 6 pieces seems to be a little more manageable, although this AI is still kicking my ass.
