Add package.json for publishing to npm

[emilbayes]

Hi Daniel,

Awesome work! I've made this pull request to make it easier for people using node.js module loading system to overload css @import statements. It makes it a lot easier to manage dependencies such as icons fonts in ones projects. Eg.

@import 'entypo';

.view-details {
  font-family: 'entypo';
  //...
}

I've prepared the package.json file for you, and all you need to do is to publish it to the npm registry: https://www.youtube.com/watch?v=BkotrAFtBM0
