James D. Callahan III:
	- Removed SPELL_OVERWRITE_MAP - now check for recipe:PreviousRankID() instead.
	- Recipe dumps will now include recipe:SetPreviousRankID() where appropriate.
	- Updated Leatherworking and Tailoring recipes to use recipe:SetPreviousRankID()
	- Added recipe_prototype methods SetPreviousRankID and PreviousRankID; this is much cleaner (as a one-to-one mapping) than maintaining a monolithic SPELL_OVERWRITE_MAP.
	- Display tweak.
	- Actually remove the textures…
	- Removed the profession textures we were shipping with in favor of SetPortraitToTexture() and GetTradeSkillTexture()
	- Use BOOKTYPE_PROFESSION rather than "profession".
	- Made the search box inherit from SearchBoxTemplate.
	- Made search-on-type more responsive.
	- ChangeLog update.
