Yarn packages

[MMakali]

some of the yarn packages are not available in the yarn registry. it would be better to switch to npm.
here is my terminal output

> [makali@some-young client]$ yarn install
> yarn install v1.2.0
> [1/4] Resolving packages...
> [2/4] Fetching packages...
> error An unexpected error occurred: "https://registry.yarnpkg.com/postcss-discard-comments.js/-/postcss-discard-comments.js-2.0.4.tgz: Request failed \"404 Not Found\"".

I fixed that bug a while back, had to regenerate the yarn config files. I dont think I pushed the changes though, will do that now
