Add Location.setDirection(Vector). Adds BUKKIT-4862

This commit adds an additional method to Location to set the direction of
facing. Included are a set of unit tests that ensure the consistency of
getDirection and setDirection using a set of cardinal directions and
arbituary data points.

Javadocs were also added to pitch and yaw methods that explain the unit
and points of origin.

Pulled from PR #979
Specify MaterialData for Acacia and Dark Oak stairs. Fixes BUKKIT-5037

When Minecraft 1.7 was released, Acacia and Dark Oak Stairs were added.
While Bukkit added them to Material.java, it did not add the MaterialData
mapping of them to Stairs.class.

Currently getAscendingDirection() and other stair-specific functions can
not be used on these new stairs. This commit fixes that by adding the
mapping needed.
