McDonald's cdkickstart.com website

I've gone through each of the pages and made various changes so they talk about CD rather than BDD. In some places I factored out some variables/parameters etc, in other places I just made a new version of the whole page.

We can obviously iterate on the content.

2 things to do: 
* make hello@cdkickstart.com email address work
* check the integration with twitter, disqus etc - not sure how that works and if it'll work for CD.
