James D. Callahan III:
	- Set BattleNet notes that are empty strings to nil, so the column won't render when nobody in the list has a note.
	- Display empty BattleNet Info lines as "Unknown"
	- Shifted the RealID name column over and set it to span two columns to fix the layout after the addition of the class column for WoW friends/guildies.
	- Removed Guild Level display - this is going away in two months with WoD.
	- Added a sortable class column.
	- Use LOCALIZED_CLASS_NAMES_FEMALE and LOCALIZED_CLASS_NAMES_MALE instead of building them out locally.
