* Added automap.go stub
* Handle errors in original AutoMap.txt file
* Completed AutoMapRecord struct and comments
* AutoMap loader implemented
* Update from base repo
* Comments added to d2netpacket and d2netpackettype.

* more d2map refactor
adding realm init to game client
passing map engine from client and server into realm at init

put exports into d2client.go and d2server.go
kept GameClient and GameServer methods into their respective files
made methods for packet handlers instead of the giant switch statements
