Utilized the private AddOn "namespace" made available in 3.3 and named it "private" - now I'll have to write a proper API for AddOns which want data since direct access is now impossible.

Moved addon.WHATEVER_list to private.WHATEVER_list.
Removed file-local RecipeList, CustomList, etc - now using the private lists only where absolutely needed.
Re-named and changed the usage for many more table members: vendor["SellList"] became vendor.sells, acquire[index]["Type"] became acquire[index].type, etc.
