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`.

WARNING: This may break some custom skins!

  `.drawer > .contents` has been moved to
  `.drawer > .drawer__pager > .drawer__iner`, and the waves have been moved
  from `.drawer > .contents` to `.drawer__inner__mastodon`!

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.
