Head Slot 1&2 homogeneity

[Shadowstar]

Simply this, all head slot items (like glasses, headbands, mouthpieces, etc) can be available in either slot 1 or 2, instead of different items for each, so that we could use two slot 1 items at the same time, or two slot 2 items.  Would enable a bit more costume variety. And I specifically would like to combine the gunslinger hair ribbon with the glasses for one of my characters. 😁
