Add a bower.json

I usually use Bower and npm to manage my dependencies for projects. Bower for my web dependencies and  npm for my node dependencies. I added the required `bower.json` file in order to register a module into the Bower repository.

If this is something you would like to do, refer to this page for how to do it http://bower.io/#registering-packages

`bower register luv.js https://github.com/kikito/luv.js` I think would be the command after merging.  :thumbsup:
