Better Stairs

---

Overview

Put stairs back in the crafting grid to convert them to/from a smarter variation of themselves. Inside corners, outside corners, and sideways corners, right side up or upside down, and sneak click to rotate. Supports all vanilla stair types.

The really crappy trailer video sort of explains how they work (hint - it's sometimes based on the neighbor, and sometimes based on the angle you are facing.  Probably best to practice a bit in creative mode).
