Move legacy item 'Glasses' to a different paperdoll layer

[Nördlich]

Can the glasses be moved from layer 6 / 0x06 (hats) to 18 / 0x12 (earrings), as is the case with eyepatches? This would allow us to wear glasses without sacrificing the hat slot.

[Alteripseity]

This is fine. We'll work toward slotting it in elsewhere.
