Additional context

This looks mostly fine except for Shii-Cho, adding every sword category is going to add way more weapons than it had before. For now it should probably just use the Japanese_swords category instead.

This PR doesn't change any style weapons, it's just line condensation 🤔
I'll put the seperate list back in for Shii-Cho's own PR.

Oh sorry, for some reason I confused this with a different PR that added the weapon categories to all these.
