`popover-content` class had no effect on emoji popover since
it was resetting `padding: 0` and background color was
already applied by tippy theme.
In short, removing `popover-content` had no visual changes.
postcss-preset-env transpiles this back as necessary. (It does a
better job than we did, in fact: we had several four-argument hsl()
calls that should have been hsla().)

Ever since we started bundling the app with webpack, there’s been less
and less overlap between our ‘static’ directory (files belonging to
the frontend app) and Django’s interpretation of the ‘static’
directory (files served directly to the web).
Split the app out to its own ‘web’ directory outside of ‘static’, and
remove all the custom collectstatic --ignore rules. This makes it
much clearer what’s actually being served to the web, and what’s being
bundled by webpack. It also shrinks the release tarball by 3%.
