Module:Item acquisition


-- Item table
-- 
-- Creates various item tables from cargo queries. 
-- 
-- 
-- Todo list
-- ---------
-- * Handle table columns that can have multiple cargo rows, preferably 
--   in one or two queries. Not per column AND row.
-- * Handle template include size? Remove item link when getting close 
--   to the limit? 
-- * Add a wrapper around f_item_link to be able to disable all 
--   hoverboxes, to avoid running into template expansion size issues.
