2. Further game messages which are incomplete/not fully reversed/partly unknown:
--------------------------------------------------------------------------------
These messages are assigned with the newusermsg servermessage, thus you can add
them to your dynamic table and (in most cases) skip them due to the
default_msg_length field. Once their structure is know we can add them to the
supported list and properly parse their information.
