use Webpack instead of Grunt; add a standalone version without locales;

[mtkcs]

This PR fixes issue #43, no breaking changes were introduced.

The changes

• Replaced Grunt with Webpack
• Extracted the main logic into core.js file
• Created a new file lib/standalone.js that exposes the main functionality of the library without including all the locale files
• For the standalone version no locales were added, so the user have to import/create a locale object ( even for english ).
• Generated dist/written-number.standalone.js and dist/written-number.standalone.min.js
• Copied the i18n folder to the dist folder at build time
• Example usage:

import fr from 'lib/i18n/fr.json';
import writtenNumber from 'lib/standalone.js';
writtenNumber(1234, {lang: 'fr'});  // => 'mille deux cent trente-quatre'

// or
writtenNumber.defaults.lang = fr;
writtenNumber(1234);  // => 'mille deux cent trente-quatre'

Why hasn't this been merged yet? This can drastically optimize the size of this library. I use this library in a library I have made (Mass.js) and would love to reduce the cost of including it.

Hi @MeekLogic , I am working on a new library for converting numbers to letters: https://github.com/forzagreen/n2words
It's supporting 15 languages and still growing. Feel free to contribute.
