side_ponytail -> ponytail

I'm not sure how specific ponytail is, but it would make sense to link the different kind of ponytails under a single umbrella.

I personally think that the ponytail tag should be used only for styles of ponytails in which the tail goes out from the back of the head.

-1 for me too, doing all the possible aliases will just make searching hairstyles that much more complicated.

Agreed with the others.
