Theme test

I find it painful to work on the site being so ugly.

This adds a basic theme we can work off of.

Also I've split up the categories into their own section, as I don't think we can scale with simply enumerating every page on the index, so I put links to the categories on the sidebar. We can highlight some key principles on the homepage if we want.

Also I have been mispelling recipes everywhere...
