		}

	This list is used to build sortedAddonList, which is the list used in the FauxScrollFrame.

			so you can directly insert the Blizzard addon names to the list.

	- If type(addonIndex) == 'string', it will be shown in the panel as a category header.
	- The collapse state will be retrieved from the saved variables: collapsedAddons.
	- If addonIndex > GetNumAddOns(), it''s a Blizzard addon, the index references to ACP_BLIZZARD_ADDONS[addonIndex - GetNumAddOns()].
	- otherwise, addonIndex is the index used in GetAddOnInfo().

	This list will be rebuilt whenever use expanded/collapsed a category, or when user changed the sorting criteria.

	addonListBuilders : a table of functions used to build masterAddonList

	To define your own sorting criteria, check the default builder functions as examples.
	Note if you create the build function in an external scope, you cannot access to the ACP local variables,
	  i.e. masterAddonList and ACP_BLIZZARD_ADDONS, but they can be accessed through ACP. e.g.:

		function MyExternalBuilder()
			local masterAddonList = ACP.masterAddonList
			local bzAddons = ACP.ACP_BLIZZARD_ADDONS
			(Now build the masterAddonList)
		end

	When you have defined your own builder function, simple add them to the table by:

		ACP.addonListBuilders["MyExternalBuilder"] = MyExternalBuilder

	After everything is done, the custom defined function can be accessed from the ACP sorter drop down menu.
