Port 4c03e05a4e to glitch-soc
This introduces new requirements in the API:
`/api/v1/timelines/tag/:tag` now accepts new params: `any`, `all` and `none`
It now returns status matching tag :tag or any of the :any, provided that
they also include all tags in `all` and none of `none`.
Port Mastodon's hashtag stats thing to glitch-soc.
This doesn't change how hashtags are ordered, and doesn't add a trending
hashtags section, but it does change how hashtag searches are rendered,
displaying a trend line alongside each hashtag.
