Rename modules according to artifact names

test -> thirtyinch-test rx -> thirtyinch-rx rx2 -> thirtyinch-rx2 plugin -> thirtyinch-plugin logginginterceptor -> thirtyinch-logginginterceptor

Any special reasons for that? 🤔 Aren't the visitors of github.com/grandcentrix/thirtyinch aware that they are looking to thirtyinch modules?! 🙃

I consider it a best practice to name the modules like the artifacts. See okhttp for example. I'd like to be able to point to this repo to demonstrate best practices 😄
