All slabs when stacked turns into stone slab block.

Hi!

I just tried out the new snapshot, and i need to say that the terrain generation is AWESOME! But i have a problem with slabs. That's okay with stone slabs that stacks up into a stone slab block. But the others slabs, turn in... Well... a stone slab block.

Stone slab+stone slab= stone slab block.

Sandstone slab+sandstone slab(for exemple)=stone slab block.

Hope you'll correct it,

Harsane.
