A single app will still be served from a server. We'll never be a fully packaged (i.e. serverless) app like Fireplace.

I see now that we can use JS_SETTINGS in ``settings/base.py``. Could we just leave it at that and not rely on ``media/js/settings_local.js``? Adding that to media means devs have to copy one more dist file when they set up the app. It seems unnecessary to me. I like the idea of JS_SETTINGS in ``settings/base.py`` though.
