Add dev-toolkit Alternative (#300)

Adds the [`dev-toolkit` npm package](https://github.com/stoikerty/dev-toolkit) to the list of Alternatives.

After some suggestions in my last PR #292, I've changed my project to provide better command-line utilities for initializing an app. Managed to get rid of babel's dev-dependencies as well, so this is now a dependency-free project just like `create-react-app`.
