Add dummy posts to test pagination
Update images
Move theme styling into base stylesheet

- Also remove CodeRay styles and imports
Add Highlight.js syntax highlighting

- Much better results than CodeRay, and lower maintenance
- To add a syntax-highlighted code block, use fenced code blocks with
  ~~~. The language of the contained code will be automatically
  detected.
- To make the language explicit, append it to the opening fence:
  ~~~ruby
- The color scheme is set in _config.yml.
- For a complete list of available themes and languages, see the
  Highlight.js website: http://highlightjs.org.
Add workaround for pagination bug

- paginator wasn't working as expected, generating bad links to paginated
  blog index pages.

- Added a liquid tag to the index template to append the pagination
  directory to the href url for the "older posts"/"newer posts" links.

- `paginate_directory` is set in `_config.yml`
