Subject: [PATCH] Enable local consumption of OUI (#813)

* Fix linting sass files

With the upgrade os `eslint`, the location of the default formatter changed. This is just a hack to work around the problem in the now abandoned `sass-lint`.

Signed-off-by: Miki <miki@amazon.com>

* Add preinstall script
