Merge upstream changes through 88f22f2e

This was not a straightforward merge. A new method was added upstream to: worldedit-core/src/main/java/com/sk89q/worldedit/world/block/BlockType.java This file has been substantially changed vs upstream worldedit. I merged things as best I could - added the new method to this interface, and then implemented it in: worldedit-core/src/main/java/com/sk89q/worldedit/world/block/BlockTypes.java Unfortunately there's no easy way to test that it works - so I left a note...
