Merge remote-tracking branch 'origin/master' into gs-master

  Conflicts:
 	app/javascript/mastodon/locales/en.json
 	app/javascript/mastodon/locales/ja.json
 	app/javascript/mastodon/locales/pl.json

The above conflicts appear to be a text conflict introduced by
glitch-soc's additional level of columns (i.e. moving a bunch of columns
under the Misc option).  They were resolved via accept-ours.
