			uint32 SourceZoneID
			uint32 SourceInstanceID
			char OriginatingCharacterName[0]
			- Null terminated name of the character this packet came from. This could be just
			- an empty string if it has no meaning in the context of a particular packet.
			uint32 Type

			The 'Type' field is a 'sub-opcode'. A value of 0 is used for the LFGuild packets. The next feature to be added
			to queryserv would use 1, etc.

			Obviously, any fields in the packet following the 'Type' will be unique to the particular type of packet. The
			'Generic' in the name of this ServerOP code relates to the four header fields.
