Subject: [PATCH] Fix some recipe book bugs
Fix written books crashing the server. Fixes BUKKIT-4945
Fix BlockCanBuildEvent returning null. Fixes BUKKIT-4972
Due to obfuscation changes in 1.7.2, "l" is now the Material ID.
i j and k became the x y z coordinates, resulting in no ID being matched
for the Material.
This is corrected by swapping the values into the correct order.
