Bukkit

• Added WorldGuard region support:

- Monsters now conform to the mob-attack flag

- Monsters now conform to the mob-spawn flag, including ALL spawns EXCEPT from spawner blocks

- Death explosions, creeper explosions, and ghast fireball explosions all conform the creeper-explosion flag

- Zombie block attacks and corpse piles will ONLY occur if the passthrough flag is set to allow (non-regions by default, as well as regions with allow)

• Added Zombie Corpse Piling:

- When a zombie has been alive, targeting a player, and below a player, unable to reach any blocks to break, it will die and leave behind a block representing its corpse.

- Defaulted to 50 seconds minimum frustration time, and Gravel block.

- Sky fortresses are no longer foolproof!

• Added a toggle for whether Zombie Block Attacks actually drop the block itself.
• Split the damage from hp nodes in order to facilitate more plugin compatibility. Will work the same as before with both enabled.
• More Zombie Block Attack algorithm improvements.
• Fixed a bug where Zombies were breaking blocks when they can't see a player.
• Fixed a bug where Zombie Pigmen were breaking blocks like Zombies.
• Added a config setting to bring back the Pigman block breaking bug.
• Added additional support for config errors.
