HalpLibe

• Add extra handle in NetworkMessage to filter execution Environment.
• Added TextureHelper.
• Delay item stats init.
• Added ItemStack and UUID write/read methods in UniversalPacket.
• Add compatibility methods for sending NetworkMessage when halplibe is not installed on the receiver.
• Removed SoundHelper as it did not do anything anymore.
