James D. Callahan III:
	- keystoneIDToRaceID => KeystoneIDToRace, keystoneLootRaceID => lootedKeystoneRace
	- Make sure currentDigsite isn't nil before attempting to record looted keystones. Should really only happen if the UI was reloaded before loot was grabbed.
	- Replaced HasArchaeology() with private.hasArchaeology - set in OnEnable() and updated whenever SKILL_LINES_CHANGED fires.
	- When announcing projects that were just solved or can be solved, include the project's icon.
