Updated tmwAthena network protocol

* The code defining the message IDs and sizes are now generated by the
  tools/protocol.py script in the tmwAthena repository.

* Reduced client version from 20 to 6, because that is currently the
  minimum supported version, and any adjustments needed for later likely
  still need to be made.

* Removed use of no longer handled messages:
  - CMSG_SKILL_USE_BEING
  - CMSG_SKILL_USE_POSITION
  - CMSG_SKILL_USE_MAP
  - SMSG_PARTY_MOVE
  - CMSG_WHO_REQUEST
  - SMSG_WHO_ANSWER
  - SMSG_MVP
  - SMSG_BEING_MOVE2
  - SMSG_BEING_CHANGE_LOOKS

* Some messages were renamed to match the server side
  - CMSG_PLAYER_ATTACK -> CMSG_PLAYER_CHANGE_ACT
  - CMSG_PLAYER_RESTART -> CMSG_PLAYER_REBOOT
  - SMSG_ADMIN_IP -> SMSG_BEING_IP_RESPONSE

Part of addressing issues #55 and #47, which we now know are about
handling SMSG_PLAYER_HP and SMSG_NPC_COMMAND respectively. The client
will now ignore them (with a warning) instead of crash.
