Sourcemaps for CSS

[david-crespo]

inline:1 inline:1 inline:1 inline:1 is not so useful.

When you click the link you get this, which is slightly more useful but still crappy.

Unfortunately there's a 4 year old issue and a 2 year old PR for sourcemaps that don't seem to be going anywhere, so it's not something we can just turn on. Just something to keep an eye on. Emotion has sourcemaps, so it's not impossible.

The styled-components docs do mention having component names in the generated classes, but we have that on already strangely none of the styles seem to be coming from the classes with the helpful names in them.
