* Move networkcode to a dedicated directory
* Rename clientserver.h to network/networkprotocol.h (Better name) and sanitize some includes
* Create object NetworkPacket
* It stores command (opcode) and data separated
* It also stores peer_id
* Data reading can be done by using a streaming interface
* Change packet routing analysis
* Remove old conditional analysis
* Now uses function pointed analysis and add connection state ({Client,Server}::handlers)
* Connection state permit to categorize condition to handle before analyze packets
* Create a handler for depreciated messages, instead of duplicating code
