Basic child theme skeleton

Okey-dokey, this is what I use as the base for child themes. Once this is merged into the main repo, I will push it to the server, and we can run it on the site.

To develop the theme I suggest working with a local copy of WordPress. That will require [The Bootstrap](http://wordpress.org/themes/the-bootstrap) be installed as a theme (it is in the theme repository, so you can install it from in WordPress.

We can talk about the specifics in the issue queue, but I expect that this will have the base style sheets need to reproduce the main site's style, and then we can add new style sheets to the theme. I was also thinking we could just import them from where they live on the main site, since that will pull in changes automatically. Up for discussion! ^_^
