Adds options.headers being set on any request to files within the content base

[tdeekens]

Adds support for specifying options.headers which are then set on any request to a file within the content base not just the bundles. The pull requests relates to issue #69.

A webpack.config.js such as

...
devServer: {
   headers: { "Access-Control-Allow-Origin": "*" }
}
...

would set the Access-Control-Allow-Origin entry on e.g. the index.html within the content base.

Any news on merging this in, any changes which have to be made or is it just not of interest?
