Bukkit

• Using a completely new spawning method (thanks to DarkBladee12 for the HorseModifier class)
• Horses now spawn with more natural health levels (8-15 hearts)
• Fix error when world name is not valid
• Spawned horses do not despawn (but do not force chunk to stay loaded)
• Remove all NMS code!

IMPORTANT NOTE!

All horses naturally spawned from previous versions will be removed from the world and will show an warning in console

This was unavoidable as the previous versions did not spawn the entities in the correct way! Sorry!! :(
