A way for people to screen out AI generated content, similar how people can screen out nsfw content already.

It works the same as the nsfw filter except underneath it's an integer instead of a Boolean.

Content authors will flag their content as AI-generated, on a sliding scale from 0 (no AI) to 100 (completely AI generated. Intermediate values could be used too although this amount of nuance may be confusing for some.

Users will be able to set a "AI generated threshold" which filters out content above that threshold. At the UI level this could be presented as a checkbox but maybe a slider would be good.

Mods need to be able to set the AI level on content, as they do now with NSFW content.

Communities will have an AI-gen value too, which is automatically applied to all content within. Instance admins can override this value too, for local or remote communities.

Thoughts?
