Adding documention about web publicPath

[eliperelman]

Fixes #133.

hmm is there an example of what this looks like? I just get:

TypeError: Path must be a string. Received { path: 'build', publicPath: '/' }

For:

module.exports = {
  options: {
    output: {
      path: 'build',
      publicPath: '/'
    }
  }
}

Tried just doing neutrino.options.output.publicPath = as well but seems to be a getter returning nothing, webpack is so confusing :D . For context I'm adding an example for Up which uses API Gateway, so they add /dev /prod to the path.

Hey @tj, depending on what your preset or RC file looks like:

module.exports = neutrino => {
  neutrino.config.output.publicPath('/');
};

Or

module.exports = {
  use: [
    'neutrino-preset-react',
    neutrino => neutrino.config.output.publicPath('/')
  ]
};

Something like that should work. Lemme know!

Thanks man! I'll give that a try
