Core Du Serveur Updater 928

Notable changes include:
Fixed:

Fixed random NPEs when generating a world
Made Squids fire EntityDeath events.
Fixed the EntityTame event.
We now move the Vanilla nether to Bukkit's multiworld format for easier transition to Bukkit.
Fixed players being sent to spawn and beds not working when switching from Vanilla to Bukkit.
Fixed issues with infinite items (trying to drop an infinite item would leave a stack on the ground that people could pick up infinitely).
Fixed plugin triggered player movement (like teleporting) triggering the movement speed check.
Fixed several NPEs within the World class.
Fixed hostile entities continuously targeting dead entities.
Fixed losing an infinite item when interacting with an entity.
Fixed furnaces leaving items behind when smelting.
Fixed spawn location offset.
Fixed players not healing in other worlds when spawn-monsters is false.
Changed Nether portals to be handled by a customisable PortalTravelAgent, allowing Plugins more control over portals.
Made the Block Place cancellation code for steps account for more scenarios.
Moved spawn-protection setting from server.properties to bukkit.yml (we automatically move your current setting over the first time).
Fixed PlayerPickupItem event firing even if the player could not pick up the item.
