Texture Pack update

You can grab it from here. I just updated Pistons to match the cobble much like the Furnace. Edited Sticky pistons as well, making them a bit cleaner. Tried to redo wooden doors and see if it looks good, personally I am 50/50 about it. I do like how trapdoors came out! Also temporarily 'fixed' gravel once again. I'm not sure why it's so difficult to texture, but it's funny and alright for now. Bare with me as updates push out. I have many to clean up and redo!
