Echo JS 0.11.0

Hi,

I'm sharing this little experiment. The interface is really rough but the real magic happens behind the curtain.

With it, you can download Npm packages ready to be placed in the "node_modules" folder of your project. 
This is intended to be use in area where the only internet access is possible through a web browser (proxy, hotspot ...) 

Please tell me what you think.

Ben

PS : I'm cleaning the code before publishing it on GitHub.
