This currently only supports this in emoji reactions, not in actual
emoji in message bodies, but it's a great start for people who want a
text-only view.
Tweaked to update the text by tabbott.
Fixes#3169.
The data-name attribute in this case allows for a particular settings
section element to show up when the appropriate sidebar category is
clicked (which will have the same value in the data-section key).
This separates the display settings module from the
settings_table.handlebars template.
Additionally, it fixes the node tests to search in the
static/templates/settings directory and initialize any templates in there
while running tests on the settings templates.
