Fixes#1581
* Add `{{ content }}` to `home` layout
Allow the author to add content which will appear above the list of
recent posts. This also allows the `home` layout to be extended.
Add text to index.html in tests to indicate that the content appears in
the correct spot.
* Add paragraph markup
Since this is a HTML file, proper paragraph markup is needed.
Replace sample pages with hard coded HTML and Liquid in favor of a layout that does all the heavy lifting. Assign the appropriate `layout` via YAML Front Matter and away you go.
* Cleanup syntax highlighting styles
* Replace hardcoded color values with [base16](http://chriskempson.com/projects/base16/) Sass variables
* Harmonize padding between GFM code blocks and `{% highlight %}` code blocks
* Improve readability of line numbers
* Add longer code block example to test double digit line numbers
* Adjust code block colors for specific skins
