remove alias morning_glory_(flower_knight_girl) -> asagao_(flower_knight_girl)
Cleaning up Flower Knight Girl names, transitioning them from the Japanese names for the flowers to the English names. At the moment they're a bit of a confusing mix, so either I go all English or all Japanese names, and since I used the English names for any new character tags, I wanted to keep it consistent. Of course I know that Danbooru prefers Japanese names, but these characters are supposed to be personifications of flowers.
