Jekyll version

Ok, as far as I can see the Jekyll version now does everything Master does. Please take a look and give me your feedback.

To compare the homepage, you can run jekyll with no arguments (current date), and then with `jekyll --time=2013-01-30` which should make Regular the “next meetup”. (Actually if you're looking at it Friday or later, there will be *no* next meetup, so use `--time=2013-02-28` to get Appl back.)
