[1.8]Slabs with Meta

Hi Guys

Right now I am trying to update my Mod to 1.8. Everything fine, except for my stained glass slabs. I read the tuts for slab and meta blocks, and the slabs are working, except for the textures and the slabs wont stack. I think the error is somewhere in the blockState and/or meta.

Comment to meta: I know that the max of meta is 16 (0 to 15). So I need two instances. I am not sure if the way to handle the meta is correct (i think i have to do it different but all slabs are in the inventory and the names are also correct.)

And beware of my code, it may be a bit messy
