Add font, image options.

[timkelty]

Adds a couple more options, allows exclusion with false.

Related: what do you think about grouping these under options.loaders?

  const options = merge({
    env: [],
    hot: true,
    html: {},
    publicPath: './',
    devServer: {
      hot: opts.hot !== false
    },
    polyfills: {
      async: true
    },
    minify: {},
    manifest: {},
    babel: {},
    targets: {},
    loaders: {
      html: {},
      font: {},
      image: {},
      style: {
        hot: opts.hot !== false
      }
    }
  }, opts);

Might not be necessary, but could clear up confusion (e.g. options.html vs options.loaders.html)

Using the term loaders alludes to a structure that is used internally by the preset, but which the user may not necessarily care about. I'd like to keep these top-level if possible.

[eliperelman]

Could you add these options to the docs?

[edmorley]

LGTM with docs additions :-)

[timkelty]

Yep, I'll add docs.

[timkelty]

Ok docs added.
