Changelog
* The `auto-tagger` script now looks for pixiv results on SauceNao. If only a result on pixiv was found, the script looks up the pixiv artist on Danbooru. If the artist was found on Danbooru (it checks aliases from the artist as well), it will include the artist tag from Danbooru in the tags for that post.
* You can set `set_pixiv_artist` in `config.toml` (check `config_sample.toml` or the `README`): In that case, if the artist was not found on Danbooru, it will create the pixiv artist as a tag automatically. Note that the category for that tag is hardcoded to 'artist', so you need to have a tag category 'artist' as well.
* Other tags on the pixiv post won't be included for now (maybe a character/parody lookup on Danbooru in the future)
* Add sankaku to config sample by LibertX in https://github.com/reluce/szurubooru-toolkit/pull/37
