Tag alias: hair_over_eye -> hair_over_one_eye

Reasons:

• "hair_over_one_eye" is the clearest choice, since it implies, without further explanations, that the other eye is visible; yet, some people may prefer to use "hair_over_eye" instead.

• "hair_over_one_eye" is already the main tag; "hair_over_eye" has just one post and a warning: "Use hair_over_one_eye instead."
