Network packets

- Needs additional information on Brick Hill Legacy network Packets.

Network packets are a way of contacting to the host or client via sending or receiving data. The amount of defined network packets has been changing ever since the implementation of Http Dll 2.1¹⁾ in Brick Hill Legacy Beta.

The table will be updated. There's too much stuff to describe.
