* more d2map refactor
adding realm init to game client
passing map engine from client and server into realm at init
change `generate map packet` to have act and level index as data

* fixed funcs for level data lookups
* started implementing level generator, currently crashing
* client no longer exploding

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

* towns now generate on server start, create player takes act and level id as args, levels have their own map engine

* d2common: item affixes only
removed Rare/Unique Prefix/Suffix as those are related to monsters, not items.
* removed debug print from item_affix.go
* changed item affix type names for clarity, removed debug print from data_dictionary
* d2common: item affix datadict and records
Item Affixes are defined in `/data/global/excel/Magic{Prefix,Suffix}.txt`
