Merge to upstream for any missing extension

[0Ha16wA5]

Describe why this should be added

Instead of duplicating work, why not merge it to upstream (Keiyoushi)?

Especially for extension like EveriaClubCom, Misskon, Xinmeitulu improvement, etc...

More eye to review, more code quality, more code improvement.

I did that before but some of the changes were more of my opinion so they rejected it and told me to keep it on my own repo.

Also, Komikku app now has a feature of showing related mangas which is not on Mihon so the changes which support that feature better will surely get rejected.

However, I'm still merging improvements that could be accepted to the upstream's repo.
