feat(index): add CSS Modules support (postcss-modules)

[michael-ciniawsky]

⚠️ DO NOT MERGE ⚠️

This PR is for testing purposes only and will never land in postcss-loader this way, it's goal is to publicly test, polish and gather feedback for the remaining TODO's to make CSS Modules work with postcss-loader && css-loader v1.0.0

Code in lib/modules maps to each plugin in css-modules/postcss-icss-${filename} where it finally belongs 😛

I working on upstreaming the first bits to the appropiate plugins, this PR was never intented to land in postcss-loader. I opened it for discussion and visibility for others. I have the css-webpack-plugin && css-loader && style-loader ready for polishing, but there are a few things to discuss and I will summarize them in a gist instead when the code for each package is ready for alpha testing, so it's hopefully easier to finish the remaining TODO's and find consensus
