Upgrading and optimizing the core terrain generators in preparation for upgrading the Seed generators. A process that used to take 4 minutes on a 20,000 tile map now takes ~15 seconds. Pretty sweet. 
Should get the 200x100 map gen time down to around 5 minutes. Hopefully I can wrap that up tomorrow night and then see if I can improve the processes that now take up the bulk of the generation time.
