Bukkit

This is a required update for CraftBukkit 1.4.6-R0.1 Beta, as Bukkit made numerous changes to parts of the internal class structure ProtocolLib uses to inject its custom code.

In addition, there's a number of small bug fixes - a fix for ticket-24 addresses an oversight causing written ItemStack arrays not being properly converted. I also updated the conversion of CraftItemStacks to net.minecraft.server.ItemStack in 1.4.6.

Finally, I've completely redone the packet cloning system. It should now work properly, regardless of packet ID (unlike the old system that couldn't handle ID 24, 51, 53 and 56), and is also approximately 2-3x faster.

New features

• Added a generic cloning library to properly support deepClone().
• Crash if multiple copies of ProtocolLib are running simultaneously.

Compatibility

• Added support for 1.4.6.
• Rename ObjectCloner to ObjectWriter.

Bug fixes

• Create a typed ItemStack array when writing it to a field. FIXES 24.

Small fixes

• Don't ignore critical exceptions - print them.
• Ensure that CraftItemStacks can be converted to NMS item stacks.
• Add equals() and hashcode() to the wrapped DataWatcher.
• Added StructureModifier tests for different packet types.
