Fishy's OG Pistons

Replaces the piston and sticky piston textures and models with ones that are reminiscent of the original pistons mod made for Minecraft Beta 1.6.








-Note, the animation for the sticky pistons is a little bugged, but that's because I had to work around some limitations of the game. I cannot fix it until minecraft allows the sticky piston to use a different base model when extended.
