add NodeJS and npm support

[Geal]

This project only supports Rust and cargo right now, and to get a great project, we need to support more platforms!

Here is how you can proceed:

• declare a new module for your language
• implement the Platform trait for your module, following the example code of the Rust module

For NodeJS, we should look for a package.json file in the probe() method, and call npm build and npm run in the build()and run() methods.
