I added the ability to show tweets in my posts. It's a javascript
technique, so we'll see if I keep it.

Some minor changes to colors and styles. I fixed the superscript
tag, since it was producing a ridiculously high superscript. I also
removed the light line above the naviation links. Just the bottom line
remains.

I created a new post for 2013-07-14. This is a complete first draft
that will have to be edited.
