Registered new items and added TFC Foods tab to creative menu to avoid confusion with vanilla food items
Moved some more items to TFC Foods tab
Convert references to vanilla items to their TFC counterparts
Change workbench to allow for oredict use for other mods. Add some oredict (still needs more work)
