Adds QUEEN tag to the brain blob.
Merge remote-tracking branch 'upstream/master' into issue7508_some_fixes_for_item_cutting
Remove m1 and m2 material members from item types.
Many dynamic items in game have one material, add a constructor for single material items.
Artifacts serialize their materials correctly and json loading code will handle legacy m1 and m2 json members correctly.
