Dylan K. Taylor bdd9a7eb52 Kill BatchPacket, clean up batching related things
DataPacketSendEvent and DataPacketReceiveEvent will no longer capture BatchPackets
In most places strings are now used instead of DataPackets, to remove limitations on what data can be sent to a network interface
Removed CraftingManager's cyclic dependency on Server

There is a lot more work to do aside from this, but this commit is intended to clean up what is necessary to fix the handling of BatchPacket.
