create alias minishorts -> short_shorts
utility alias consistent with minidress aliased to short_dress. May also help at least a little bit with the undertagging.
I also think the alias could be done the other way around and make minishorts the main tag, since it seems to me a more known name, at least to me. I'll take your suggestions.
