Added bundler Gemfile.
Added basic jekyll config file.
Basic layouts ported.
Basic home page ported with blog post listing.
Added default welcome blog post from jekyll.
Removed gh-pages params.json file.

No longer need this as we're using jekyll for site generation instead of
the basic generator from pages.github.com.
Added _site/ to .gitignore.

This directory is automatically generated by jekyll when serving the
page contents for testing. We don't need these files in the repository
as they're generated at jekyll runtime.

Modified headline.
Changed blog listing to use excerpts and headers.
