node-sass and includePaths

Hi, it would be awesome to support node-sass includePaths feature with this project!
In my fork I've made some changes in order to support it! I'm not pushing a request because I don't use compass, bower nor diamonds so I don't know how this affects those but I've tested it on my sass project, which uses grunt-sass (so node-sass) and it works flawlessly, it just has to be tested with other supported tools!

To support the includePaths it's pretty simple: just create a index.js file where you will export the path to the scss folder:

var path = require( "path" );

module.exports = {
  includePaths: [
    path.join( __dirname, "scss" )
  ]
};

and then in the package.json file just change the main file to index.js

In this way, I can easily install this plugin with npm and require the file in my gulp, grunt or pure node file.

Then In my scss file I just have to @import typi;

That's pretty simple!

I'm asking this because in this way code is much more mantainable! No copy-paste required!

Thank you for the suggestion, @dcdeiv. Do you mind sending a PR? That'll help me push the changes much faster.
