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.

- Preload video metadata if the video is loaded in detailed view, as it is
  likely to get played, and metadata is useful for seeking in the video.
- Preload video data if it's fullscreen as it is extremely likely to get
  played right after being put in fullscreen (although those are two steps).
- Preload video data if the user has clicked the position slider, as the video
  will play as soon as the mouse button is released, and video metadata is
  needed to properly seek into the video.

This prevents accidental text selection and avoids opening the toot containing
the video in the dynamic column when clicking on the position slider.

Ctrl+click usually allows opening a link in a new tab. This
was prevented for hashtag or user links in toots.
