Random details genration for blocks

so far we have 9 types of blocks, each with 8 difrent verations/pattens. bringing the total to 72

now i added random details that apear whenever a block gets placed down, right now there are 16 details that go over the top of the 72 patten blocks makeing the total around 1224 difrent kinda blocks... so i think if i add any more ill be overkilling it just a little bit. :P0004.png
