Allow the use of a pundle config file.

Right now, although powerful, having to manually go through the boilerplate steps of calling pundle.compile, pundle.generate, and fs.writeFileSync all in different promise blocks is a hassle. I know it's not that big of a deal, but I feel like since every other alternative offers a config file, the programmatic approach can scare newcomers away.

pundle-dev kinda solves this problem with it's server config, but that doesn't work with just pundle by itself.

It'd be nice to have something like:

export default {
  entry: ['index.js'],
  rootDirectory: './src',
  pathType: 'filePath',
  moduleDirectories: ['node_modules'],
  plugins: [
    ['babel-pundle', { config: { presets: ['steelbrain'] } }],
    'pundle-some-magical-plugin'
  ],
  loaders: [
    { extensions: ['.coffee'], loader: 'pundle-coffee' },
    { extensions: ['.less'], loader: 'pundle-less' }
  ],
  sourceMap: true,
  outputDirectory: 'lib'
}

The API for the config file would probably be different than this, but you get the idea. You could also add a server block if you instead to use this config with a server. It also carries the benefit of being more readable.

I love the idea!

This has been implemented in #75
I'll keep this open until it's merged

Fixed in Pundle v2Alpha1
