tidy-up code in templates (end of Chapter 3).

These are minor changes -- just typo's, spacing issues Etc.

I added a for-loop to index.html just to get some data in the
'content' area in the 'main content area'. This will eventually be
replaced as I move throught the various chapters. I only added it to
see how the CSS rearranges the layout when there is some 'content' in
the main part of the page.
