Bukkit

• Added the "mobdespawn" flag. This stops mobs from de-spawning naturally or being killed in protected regions with out this flag. All regions have this flag by default.
• Stopped Endermen from teleporting to regions without the "monsterspawning" flag.
• Stopped Dragon Egg's from being teleported around if the region does not have the "build" flag.
• Fixed the item frame bug that meant people could add items and rotate items in the frames, regardless of region flags.

Even if a player has permission to build in a protected region they are unable to break any item frames or paintings.
