WIP: Font awesome fix for npm > 3

[jure]

This: https://github.com/substance/lens/blob/master/styles/_lens.scss#L2 doesn't work anymore in Npm > 3. Npm > 3 flattens the dependency tree, and that means that if the lens module is installed as a dependency, then it will no longer have a nested node_modules folder with its dependencies, but those dependencies will instead be installed at the project's root node_modules.

I'm not exactly sure what the absolute best fix is, so this is a start. There is currently one Webpack specific fix at: https://github.com/jure/lens/blob/16928130bc84902482ca16afb1e558b5bd76ec39/styles/_lens.scss#L1
so this one will have to be changed to a generic solution for sure.

I imagine you do want to fix this, but if you don't want to support npm > 3, I suggest you make that clear in your package.json, by specifying a version in the engines.

Is this actually possible?

@import 'substance/packages/_all';

Like does this resolve in an npm-ish manner?

[jure]

No, sorry. This SCSS stuff is quite confusing. So SCSS does not have a way to distinguish relative paths from other imports: https://www.npmjs.com/package/sass-loader#imports

It's important to only prepend it with ~, because ~/ resolves to the home-directory. webpack needs to distinguish between bootstrap and ~bootstrap because CSS- and Sass-files have no special syntax for importing relative files. Writing @import "file" is the same as @import "./file";

It does if you're using webpack's sass-loader though, so that's why I assumed.

The bigger issue is that there is currently no way that I know of, that would enable me to use your current font-awesome integration without forking the project and using webpack specific code, such as the ~ symbol for the $fa-font-path. I'm digging into this issue now, as it will surely pop up with multiple external modules.

This is how I configure font-awesome for Lens now:
https://gitlab.coko.foundation/pubsweet/substance-components/blob/master/styles/reader.scss#L1

This works for NPM < 3, but will fail for NPM > 3. I can't see how we can make this be compatible with both versions, as the line for NPM > 3 will have to be:

@import "~font-awesome/fonts";

Which fails in NPM < 3. Ideas?

I think we can configure the SASS include path. I think that will be the way to go. Use whatever works for you atm. and we will fix that in a cleanup iteration together so it works for all the cases.
