Featured image detection refactoring: (#462)

Browse source 
We look for .Params.featured_image
If found > we use that as URL
If we find a Page resource matching the value of the above, we use its .RelPermalink
If none of the above we look for an resource whose filepath contains `featured` or `cover` and use its .RelPermalink if found

Fixes #233

For any page or post you can add a featured image by including the local path in front matter (see content in the `exampleSite/content/_readme.md` file for examples): `featured_image: '/images/gohugo-default-sample-hero-image.jpg'`
#### Featured image as Page Resources
If user is using [Page Resources](https://gohugo.io/content-management/page-resources/), the theme will try and match the `featured_image` from with a page resource of type `image` and use its relative permalink. If no `featured_image` is set, the theme will look for a Page Resource of type `image` whose filepath incudes either `cover` or `feature`
#### Other hero settings
If you would like to hide the header text on the featured image on a page, set `omit_header_text` to `true`. See `exampleSite/content/contact.md` for an example.
You don't need an image though. The default background color is black, but you can change the color, by changing the default color class in the config.toml file. Choose a background color from any on the [Tachyons](http://tachyons.io/docs/themes/skins/) library site, and preface it with "bg-"
