Vanilla Variants

 Adds numerous variants of existing blocksets. Along with stairs, slabs, and walls for most stone-based blocks.  New Block variants such as Beams allow for more creative shapes in builds and open the door for some new yet vanilla feeling builds.  Seats are craftable similar to how beds are and allow the player to sit on them by right clicking.  New Armor/Tool sets for Copper, along with every wood and stone type.
