Artist cleanup: shino_(ponjiyuusu), ponjiyuusu

For the circle ponjiyuusu, we have shino_(ponjiyuusu) and ponjiyuusu. The former consists of Rozen Maiden and Suzumiya Haruhi webcomics from here, while the latter has Touhou and links to a pixiv account. Different styles. Both link to the main site, where apparently Shino is the admin.

Do either of these artist tags need to be changed?

All indications from the website are that they're the same artist, so I've switched them all to shino_(ponjiyuusu). The style difference seems to be due to the fact that the former shino_(ponjiyuusu) stuff was web-only, whereas the ponjiyuusu stuff was from Comiket releases that the artist later released parts of on the web.
