* Added my own implementation of BlockFace, VBlockFace, to allow for more flexibility in relative blocks
* Fixed "IncludeEdges" only working along the horizonal (x & z) axis, and not along the vertical
axis
* Fixed BlockFace.NORTH_EAST being enumerated twice in the face values, and missing BlockFace.SOUTH_WEST
* "IncludeEdges" is now set to true as a default value
(Thank you to MattAKAFred on Bukkit for bringing these issues to my attention; I appreciate it greatly)
