Optionally vendor third-party dependencies

[cardi]

I'd like to deploy fluffy as a self-contained app, which would require vendoring some of the external third-party dependencies.

From a cursory search, it looks like the only dependencies are Google Fonts and jQuery.

I'm happy to work on an implementation, if you had any preferences or thoughts on how you'd prefer to go about it.

Google Fonts

This could be a flag in settings.py that would use default system fonts rather than a custom font. (Though I haven't looked at the {S,}CSS files to see how the fonts are specified.)

Maybe an easier solution would be to have a toggle for Google Fonts, and then guarding the stylesheet behind a conditional:

fluffy/fluffy/templates/layouts/base.html

Lines 7 to 11 in cb4de23

	<title>{{branding}}</title>
	<link rel="stylesheet" href="https://fonts.googleapis.com/css?family=Josefin+Slab:700|Open+Sans:wght@400;700" />
	<link rel="stylesheet" href="{{asset_url('app.css')}}" />
	<link rel="icon" href="{{asset_url('img/favicon.ico')}}" />

Then the browser would fall back to the default fonts:

fluffy/fluffy/static/scss/app.scss

Lines 12 to 15 in cb4de23

	body {
	background-color: #005178;
	font-family: "Open Sans", Helvetica, Arial, sans-serif;
	}

jQuery

For jQuery, a copy would be saved somewhere in fluffy/static/ (maybe fluffy/static/vendor/js?). jQuery is licensed MIT, which probably makes it compatible with including it in the repo.

I took a first pass at this in #191 by implementing what I thought was the most straightforward and simple approach: adding a configuration setting to load external fonts (default true) and vendoring jQuery.

Some other options to consider:

• vendoring external fonts: need to check font licenses, and possibly download via Makefile
• jQuery: maybe people don't want to host/serve jQuery and should be a configuration setting instead.
