Add glob support

[rtivital]

Currently I need to install Glob package separately to match all files in resources folder:

// webpack config
const glob = require('glob');
module.exports = {
  // ...
  sassResources: glob.sync('./src/styles/resources/**/*.scss'),
};

It would be really great if sass-resources-loader could recognize these patterns out of the box, e.g.

module.exports = {
  // ...
  sassResources: './src/styles/resources/**/*.scss',
};

@rtivital Any chance that you want to hack on the loader and put in a PR?

Sounds like a great idea.

@justin808 Well, I guess I've done it in #11

I've done some testing with provided example, everything seems just fine.
