Compatible with bukkit 1.5.1, 1.5.2, 1.4.* and 1.3.*
Issue was with an undocumented change in bukkit's definition of BlockFace. I have attempted to write code that will be compatible either way in case they change it back due to this change actually being a bug, but I cannot guarantee that it will hold up.
The /reload command is currently not supported and may cause lost of config files. I am looking into the exact cause, but for now, I recommend you stop and restart your server to avoid issues with Tetris and the many other plugins that do not support /reload.
