Usage: ./manage.py add_mock_conversation

After running the script:

From browser (ideally on high resolution screen):
* Refresh to get the rendered tweet
* Check that the whale emoji reaction comes before the thumbs_up emoji reaction
* Remove the blue box (it's a box shadow on .selected_message .messagebox-content;
  inspecting the selected element will find it fairly quickly)
* Change the color of the stream to #a6c7e5
* Shrink screen till the mypy link only just fits
* Take screenshot that does not include the timestamps or bottom edge

From image editing program:
* Remove mute (and edit) icons from recipient bar
