James D. Callahan III:
	- Fixed race for Veridian Grove Digsite
	- Added DIG_SITE_RACES table. Replaced all RACE_X variables with DIG_SITE_RACES.X lookups.
	- Applied zone name fixes submitted by cain1. Minor cleanup.
	- Follow up fix: Make the function local :P
	- Removed up value for CacheMapData, and fixed its definition to be consistent with that of other functions.
