Jack Franklin a5fd0a412d Add cssnano
The CSS minifier we currently use (clean-css) is not maintained and
lacks support for new CSS features. CSSNano is a replacement that
supports features we need (primarily container queries).

This CL only adds the relevant dependencies, and does not use it. I will
do that (and remove clean-css) in a follow-up.

# [postcss][postcss]-ordered-values
> Ensure values are ordered consistently in your CSS.
## Install
With [npm](https://npmjs.org/package/postcss-ordered-values) do:
```
npm install postcss-ordered-values --save
```
## Example
Some CSS properties accept their values in an arbitrary order; for this reason,
it is entirely possible that different developers will write their values in
different orders. This module normalizes the order, making it easier for other
modules to understand which declarations are duplicates.
### Input
```css
h1 {
border: solid 1px red;
border: red solid .5em;
border: rgba(0, 30, 105, 0.8) solid 1px;
border: 1px solid red;
}
```
### Output
```css
h1 {
border: 1px solid red;
border: .5em solid red;
border: 1px solid rgba(0, 30, 105, 0.8);
border: 1px solid red;
}
```
