HM3: Mask eyes

I've just updated the "Standard" set of "Eyes" with four or five new entries meant to serve as eye holes for masks, either the ones in "Headgear Standard" or if you're using one of the basic Head shapes as a full-face mask. I've only played around with it a bit but you can get some really nice effects. Let me know if it's working for you, and if there are other shapes you would want to see.
